General Description
1.4.13 Port D Input-Only Pins (PTD6/IS3–PTD4/IS1 and PTD3/FAULT4–PTD0/FAULT1)
PTD6/IS3–PTD4/IS1 are special function input-only port pins that also serve as
current sensing pins for the pulse-width modulator module (PWMMC).
PTD3/FAULT4–PTD0/FAULT1 are special function port pins that also serve as
fault pins for the PWMMC. See Section 12. Pulse-Width Modulator for Motor
Control (PWMMC) and Section 10. Input/Output (I/O) Ports (PORTS).
1.4.14 PWM Pins (PWM6–PWM1)
PWM6–PWM1 are dedicated pins used for the outputs of the pulse-width
modulator module (PWMMC). These are high-current sink pins. See Section 12.
Pulse-Width Modulator for Motor Control (PWMMC) and Section 19. Electrical
Specifications.
1.4.15 PWM Ground Pin (PWMGND)
PWMGND is the ground pin for the pulse-width modulator module (PWMMC). This
dedicated ground pin is used as the ground for the six high-current PWM pins. See
Section 12. Pulse-Width Modulator for Motor Control (PWMMC).
1.4.16 Port E I/O Pins (PTE7/TCH3A–PTE3/TCLKA and PTE2/TCH1B–PTE0/TCLKB)
Port E is an 8-bit special function port that shares its pins with the two timer
interface modules (TIMA and TIMB). See Section 16. Timer Interface A (TIMA),
Section 17. Timer Interface B (TIMB), and Section 10. Input/Output (I/O) Ports
(PORTS).
1.4.17 Port F I/O Pins (PTF5/TxD–PTF4/RxD and PTF3/MISO–PTF0/SPSCK)
Port F is a 6-bit special function port that shares two of its pins with the serial
communications interface module (SCI) and four of its pins with the serial
peripheral interface module (SPI). See Section 15. Serial Peripheral Interface
Module (SPI), Section 13. Serial Communications Interface Module (SCI), and
Section 10. Input/Output (I/O) Ports (PORTS).
