Section 9 I/O Ports
In modes 5 to 7, when a P2DDR bit is cleared to 0 (selecting generic input), if the corresponding
bit from P2₇PCR to P2₀PCR is set to 1, the input pull-up MOS is turned on.
P2PCR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
Table 9.4 summarizes the states of the input pull-up transistors.
