Description
Reserved
Undefined value is read from this bit.
Stores the output data for the pin that is used as the
general output port.
Reserved
Undefined values are read from these bits.
Store the output data for the pins that are used as the
general output port.
Description
Reserved
Undefined value is read from this bit.
When this register is read, the pin states are read.
Since this register is allocated to the same address as
PFDDR, writing to this register writes data to PFDDR
and the port F setting is changed.
