17.3.3
The PCDDR determines the signal direction of each parallel port pin programmed as a GPIO port in the
PCCNT.
17.4
These 16-bit bidirectional registers are used to read or write the logic states of the GPIO lines. This register
has no effect on pins not configured for general-purpose I/O.
After a system reset, these register bits are all cleared. When any port lines are configured as outputs, a
logic zero appears on those pins, unless the data register is written with an initial data value prior to setting
the pin direction.
The reset values given in the following register diagrams are the port output values written to the registers
during reset, and do not reflect the value of a register read cycle. Register reads always return the
instantaneous value of the corresponding pins.
17.4.1
In the following description PxDAT refers to PADAT, PBDAT, or PCDAT.
The PxDAT value for inputs corresponds to the logic level at the pin; for outputs, the value corresponds to
the logic level driven onto the pin. Note that PxDAT has no effect on pins which have not been configured
for GPIO.
