Section 8 I/O Ports
In modes 5 to 7, when a P5DDR bit is cleared to 0 (selecting generic input), if the corresponding
bit in P5PCR is set to 1, the input pull-up 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 8.9 summarizes the states of the input pull-ups in each mode.
