Output

Input,

internal

pull-up

enabled

Port A GPIO — This GPIO pin can be individually programmed as

an input or output pin.

PWM1 — This is one of the six PWM output pins.

After reset, the default state is GPIOA1.

GPIOA2

Input,

internal

pull-up

enabled

Port A GPIO — This GPIO pin can be individually programmed as

an input or output pin.

PWM2 — This is one of the six PWM output pins.

After reset, the default state is GPIOA2.

GPIOA3

Input,

internal

pull-up

enabled

Port A GPIO — This GPIO pin can be individually programmed as

an input or output pin.

PWM3 — This is one of the six PWM output pins.

After reset, the default state is GPIOA3.

GPIOA4

22

(PWM4)

Input/

Output

Output

Input,

internal

pull-up

enabled

Port A GPIO — This GPIO pin can be individually programmed as

an input or output pin.

PWM4 — This is one of the six PWM output pins.

(TA21)

(FAULT12)

Input/

Output

Input

TA2 — Timer A, Channel 2

Fault1 — This fault input pin is used for disabling selected PWM

outputs in cases where fault conditions originate off-chip.

After reset, the default state is GPIOA4. The peripheral functionality

is controlled via the SIM. See Section 6.3.16.

1The TA2 signal is also brought out on the GPIOB2-3 pin.

2The Fault1 signal is also brought out on the GPIOB4 pin.
