Section 9 I/O Ports
In modes 5 to 7, when a P5DDR bit is cleared (selecting the input port function), if the
corresponding bit in P5PCR is set up 1, the input pull-up MOS transistor is turned on.
P5PCR is initialized to H'F0 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting.
Table 9.9 summarizes the states of the input pull-ups MOS in each mode.
