General Description
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
Chapter 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
Chapter 16 Timer Interface A
(TIMA),
Chapter 17 Timer Interface B
(TIMB), and
Chapter 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
Chapter 15 Serial
Peripheral Interface Module
(SPI),
Chapter 13 Serial Communications Interface Module
(SCI), and
Chapter 10 Input/Output (I/O) Ports
(PORTS).
