Section 23 Pin Function Controller (PFC)
23.1.10 Port F I/O Register (PFIOR)
PFIOR is a 16-bit readable/writable register that selects the I/O direction for the port F pins. Bits
PF7IOR to PF0IOR correspond to pins PF7 to PF0, respectively. PFIOR is enabled when the
function of the port F pins is set to general-purpose I/O (PF7 to PF0) by PFCR, and are disabled in
other cases. When a bit in PFIOR is set to 1, the corresponding pin is set to output, and when set
to 0, the pin is set to input.
Bits 15 to 8 in PFIOR are reserved. These bits are always read as 0. The write value should always
be 0.
PFIOR is initialized to H'0000 by a power-on reset or by switching to deep standby mode. This
register is not initialized either by a manual reset or by switching to sleep mode or software
standby mode.
