Input/Output (I/O) Ports
Port A
Port A is an 8-bit special function port that shares all of its pins with the
keyboard interrupt (KBI) module. Each port A pin also has a software
configurable pullup device if the corresponding port pin is configured as a
general-purpose input port pin. PTA0–PTA5 and PTA7 has direct LED drive
capability.
NOTE:
PTA0–PTA5 pins are available on 28-pin and 32-pin packages only.
PTA7 pin is available on 32-pin packages only.
Port A Data Register
PTA[7:0] — Port A Data Bits
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.
