Port 5 Input Pull-Up MOS Control Register (P5PCR)
P5PCR is an 8-bit readable/writable register that controls the MOS input pull-up MOS transistors
in port 5.
Bits 7 to 4 are reserved. They cannot be modified and are always read as 1.
In modes 5 to 7, when a P5DDR bit is cleared to 0 (selecting generic input), if the corresponding
bit from P5
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.
