Table 8.26 Port A Registers
Name
Port data register A
Port control register A
Port Data Register A (PDRA)
PDRA is an 8-bit register that stores data for port A pins PA
PCRA bits are set to 1, the values stored in PDRA are read, regardless of the actual pin states. If
port A is read while PCRA bits are cleared to 0, the pin states are read.
Upon reset, PDRA is initialized to H'F0.
