7.3.4
Port 2 has built-in programmable input pull-up transistors that are available in modes 2 and 3. The
pull-up for each bit can be turned on and off individually. To turn on an input pull-up in mode 2 or
3, set the corresponding P2PCR bit to 1 and clear the corresponding P2DDR bit to 0. P2PCR is
cleared to H'00 by a reset and in hardware standby mode, turning all input pull-ups off. In software
standby mode, the previous state is maintained.
Table 7.5 indicates the states of the input pull-up transistors in each operating mode.

Notes: Off:
On/off: The input pull-up transistor is on if P2PCR = 1 and P2DDR = 0, but off otherwise.
