Port F Data Direction Register (PFDDR)
Modes 4 to 6
Mode 7
PFDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port F. PFDDR cannot be read; if it is, an undefined value will be read.
PFDDR is initialized by a reset, and in hardware standby mode, to H'80 in modes 4 to 6, and to
H'00 in mode 7. It retains its prior state in software standby mode. The OPE bit in SBYCR is used
to select whether the bus control output pins retain their output state or become high-impedance
when a transition is made to software standby mode.
