18.2
18.2.1
Port control register A (PCTRA) is a 32-bit readable/writable register that controls the
input/output direction and pull-up for each bit in the 16-bit port A (port 15 pin to port 0 pin). As
the initial value of port data register A (PDTRA) is undefined, all the bits in the 16-bit port A
should be set to output with PCTRA after writing a value to the PDTRA register.
PCTRA is initialized to H'00000000 by a power-on reset. It is not initialized by a manual reset or
in standby mode, and retains its contents.
