14.3.1 Port A Data Register
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
Port A is a 7-bit, general-purpose, bidirectional I/O port.
The port A data register (PTA) contains a data latch for each of the eight
port A pins.

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.
