18.3.1 Port A Data Register (PTA)
Data Sheet

Alternative Function:
Address:
Port A is an 8-bit special function port that shares four of its port pins with
the analog-to-digital converter (ADC) module and four of its port pins
with the keyboard interrupt module (KBI).
The port A data register contains a data latch for each of the eight port A
pins.
PTA[7:0] — Port A Data Bits
KBI[3:0] — Keyboard Interrupt Channels 3 to 0
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.
KBI[3:0] are pins used for the keyboard interrupt input. The
corresponding input, KBI[3:0], can be enabled in the keyboard
interrupt enable register, KBIER. Port pins used as KBI input will
override any control from the port I/O logic. See
