Section 18 I/O Ports
18.6.2
Port F data register (PFDR) is an 8-bit register composed of a 1-bit readable register and a 7-bit
readable/writable register. This register stores data for pins PTF6 to PTF0. PF6DT to PF0DT bit
corresponds to PTF6 to PTF0 pin. When the function is general input port, if the port is read the
corresponding pin level is read.
PFDR is initialized by a power-on reset, after which the general input port function (pull-up MOS
on) is set as the initial pin function, and the corresponding pin levels are read. It retains its
previous value in standby mode and sleep mode, and in a manual reset.

Description
Table 18.6 shows the function of PFDR.
Write
Can be written to PFDR but does not affect
the pin state.
A value to be written is output from the pin.
Can be written to PFDR but does not affect
the pin state.
Can be written to PFDR but does not affect
the pin state.
