Port A GPIO — This GPIO pin can be individually programmed as 
an input or output pin.
PWM3 — The PWM channel 3.
TXD — The SCI transmit data output or transmit/receive in single 
wire operation.
EXTAL — External Crystal Oscillator Input. This input can be 
connected to a 32.768 kHz or 1–16 MHz external crystal or ceramic 
resonator. When used to supply a source to the internal PLL, the 
crystal/resonator must be in the 4 MHz to 8 MHz range. Tie this pin 
low or configure as GPIO if XTAL is being driven by an external 
clock source.
If using a 32.768 kHz crystal, place the crystal as close as possible 
to device pins to speed startup.
After reset, the default state is GPIOA3.

FAULT1 — PWM fault input 1used for disabling selected PWM 
outputs in cases where fault conditions originate off-chip.
TIN2 — Dual timer module channel 2 input
After reset, the default state is GPIOA4.

FAULT2 — PWM fault input 2 used for disabling selected PWM 
outputs in cases where fault conditions originate off-chip.
EXT_SYNC — When not being used as a fault input, this pin can be 
used to receive a pulse to reset the PWM counter or to generate a 
positive pulse at the start of every PWM cycle.
TIN3 — Dual timer module channel 3 input
After reset, the default state is GPIOA5.
