Input/Output (I/O) Ports
13.2 Port A
Port A is an 8-bit general-purpose bidirectional I/O port with software configurable pullups, and it shares
its pins with the keyboard interrupt module (KBI).
13.2.1 Port A Data Register
The port A data register contains a data latch for each of the eight port A pins.
PTA[7:0] — Port A Data Bits
KBA7–KBA0 — Keyboard Interrupts
170
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 keyboard interrupt enable bits, KBA7–KBA0, in the keyboard interrupt enable register (KBIER),
enable the port A pins as external interrupt pins and the internal pullup of the corresponding pin. (See
