Function:
Alternate
Address:
Port A is an 8-bit special-function port that shares all eight of its pins with
the pulse width modulator (PWM).
The port A data register (PTA) contains a data latch for each of the eight
port A pins.
PTA7–PTA0 — Port A Data Bits
PWM15–PWM8 — PWM Outputs 15–8
Reset:
Read:
Write:
These read/write bits are software programmable. Data direction of
each port A pin is under the control of the corresponding bit in data
direction register A. Reset has no effect on port A data.
The PWM output enable bits PWM15E–PWM8E, in PWM control
register 2 (PWMCR2) enable port A pins as PWM output pins. (See
