Subject: [PATCH] Make LPC1768 pinmapping not specific to Re-ARM (#8063)
* Merging early because of build failures. See #8105
* Make LPC1768 pinmapping not specific to Re-ARM
* Add HAL_PIN_TYPE and LPC1768 pin features
* M43 Updates
* Move pin map into pinsDebug_LPC1768.h
* Incorporate comments and M226
* Fix persistent store compilation issues
* Update pin features
* Update MKS SBASE pins
* Use native LPC1768 pin numbers in M42, M43, and M226

+/**
+ * This is a hybrid system.
+ *
+ * The PWM1 module is used to directly control the Servo 0, 1 & 3 pins. This keeps
+ * the pulse width jitter to under a microsecond.
+ *
+ * For all other pins the PWM1 module is used to generate interrupts. The ISR
+ * routine does the actual setting/clearing of pins. The upside is that any pin can
+ * have a PWM channel assigned to it. The downside is that there is more pulse width
+ * jitter. The jitter depends on what else is happening in the system and what ISRs
+ * prempt the PWM ISR. Writing to the SD card can add 20 microseconds to the pulse
+ * width.
+ */
+
+/**
+ * The data structures are setup to minimize the computation done by the ISR which
+ * minimizes ISR execution time. Execution times are 2.2 - 3.7 microseconds.
+ *
+ * Two tables are used. active_table is used by the ISR. Changes to the table are
+ * are done by copying the active_table into the work_table, updating the work_table
+ * and then swapping the two tables. Swapping is done by manipulating pointers.
+ *
+ * Immediately after the swap the ISR uses the work_table until the start of the
+ * next 20mS cycle. During this transition the "work_table" is actually the table
+ * that was being used before the swap. The "active_table" contains the data that
+ * will start being used at the start of the next 20mS period. This keeps the pins
+ * well behaved during the transition.
+ *
+ * The ISR's priority is set to the maximum otherwise other ISRs can cause considerable
+ * jitter in the PWM high time.

+/**
+ * Almost all changes to the hardware registers must be coordinated with the Match Register 0 (MR0)
+ * interrupt. The only exception is detaching pins. It doesn't matter when they go
+ * tristate.
+ *
+ * The LPC1768_PWM_init routine kicks off the MR0 interrupt. This interrupt is never disabled or
+ * delayed.
+ *
+ * The PWM_table_swap flag is set when the firmware has swapped in an updated table. It is
+ * cleared by the ISR during the MR0 interrupt as it completes the swap and accompanying updates.
+ * It serves two purposes:
+ * 1) Tells the ISR that the tables have been swapped
+ * 2) Keeps the firmware from starting a new update until the previous one has been completed.
+ *
+ * The PWM_MR0_wait flag is set when the firmware is ready to swap in an updated table and cleared by
+ * the ISR during the MR0 interrupt. It is used to avoid delaying the MR0 interrupt when swapping in
+ * an updated table. This avoids glitches in pulse width and/or repetition rate.
+ *
+ * The sequence of events during a write to a PWM channel is:
+ * 1) Waits until PWM_table_swap flag is false before starting
+ * 2) Copies the active table into the work table
+ * 3) Updates the work table
+ * NOTES - MR1-MR6 are updated at this time. The updates aren't put into use until the first
+ * MR0 after the LER register has been written. The LER register is written during the
+ * table swap process.
+ * - The MCR mask is created at this time. It is not used until the ISR writes the MCR
+ * during the MR0 interrupt in the table swap process.
+ * 4) Sets the PWM_MR0_wait flag
+ * 5) ISR clears the PWM_MR0_wait flag during the next MR0 interrupt
+ * 6) Once the PWM_MR0_wait flag is cleared then the firmware:
+ * disables the ISR interrupt
+ * swaps the pointers to the tables
+ * writes to the LER register
+ * sets the PWM_table_swap flag active
+ * re-enables the ISR
+ * 7) On the next interrupt the ISR changes its pointer to the work table which is now the old,
+ * unmodified, active table.
+ * 8) On the next MR0 interrupt the ISR:
+ * switches over to the active table
+ * clears the PWM_table_swap and PWM_MR0_wait flags
+ * updates the MCR register with the possibly new interrupt sources/assignments
+ * writes to the PCR register to enable the direct control of the Servo 0, 1 & 3 pins by the PWM1 module
+ * sets the PINSEL3 register to function/mode 0x2 for the Servo 0, 1 & 3 pins
+ * NOTE - PCR must be set before PINSEL
+ * sets the pins controlled by the ISR to their active states

-/**
- * Almost all changes to the hardware registers must be coordinated with the Match Register 0 (MR0)
- * interrupt. The only exception is detaching pins. It doesn't matter when they go
- * tristate.
- *
- * The LPC1768_PWM_init routine kicks off the MR0 interrupt. This interrupt is never disabled or
- * delayed.
- *
- * The PWM_table_swap flag is set when the firmware has swapped in an updated table. It is
- * cleared by the ISR during the MR0 interrupt as it completes the swap and accompanying updates.
- * It serves two purposes:
- * 1) Tells the ISR that the tables have been swapped
- * 2) Keeps the firmware from starting a new update until the previous one has been completed.
- *
- * The PWM_MR0_wait flag is set when the firmware is ready to swap in an updated table and cleared by
- * the ISR during the MR0 interrupt. It is used to avoid delaying the MR0 interrupt when swapping in
- * an updated table. This avoids glitches in pulse width and/or repetition rate.
- *
- * The sequence of events during a write to a PWM channel is:
- * 1) Waits until PWM_table_swap flag is false before starting
- * 2) Copies the active table into the work table
- * 3) Updates the work table
- * NOTES - MR1-MR6 are updated at this time. The updates aren't put into use until the first
- * MR0 after the LER register has been written. The LER register is written during the
- * table swap process.
- * - The MCR mask is created at this time. It is not used until the ISR writes the MCR
- * during the MR0 interrupt in the table swap process.
- * 4) Sets the PWM_MR0_wait flag
- * 5) ISR clears the PWM_MR0_wait flag during the next MR0 interrupt
- * 6) Once the PWM_MR0_wait flag is cleared then the firmware:
- * disables the ISR interrupt
- * swaps the pointers to the tables
- * writes to the LER register
- * sets the PWM_table_swap flag active
- * re-enables the ISR
- * 7) On the next interrupt the ISR changes its pointer to the work table which is now the old,
- * unmodified, active table.
- * 8) On the next MR0 interrupt the ISR:
- * switches over to the active table
- * clears the PWM_table_swap and PWM_MR0_wait flags
- * updates the MCR register with the possibly new interrupt sources/assignments
- * writes to the PCR register to enable the direct control of the Servo 0, 1 & 3 pins by the PWM1 module
- * sets the PINSEL3 register to function/mode 0x2 for the Servo 0, 1 & 3 pins
- * NOTE - PCR must be set before PINSEL
- * sets the pins controlled by the ISR to their active states
