Table 8.29 shows the port A register configuration.

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
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.
Port Control Register A (PCRA)
PCRA is an 8-bit register for controlling whether each of the port A pins PA
an input or output pin. Setting a PCRA bit to 1 makes the corresponding pin an output pin, while
clearing the bit to 0 makes the pin an input pin. The settings in PCRA and in PDRA are valid only
when the corresponding pin is designated in LPCR as a general I/O pin.
Upon reset, PCRA is initialized to H'F0.
PCRA is a write-only register. All bits are read as 1.
