9.3.4 Input Pull-Up Transistors
Port 5 has built-in MOS pull-up transistors that can be controlled by software. These input pull-up
transistors can be used in modes 1 and 2. They can be turned on and off individually.
In modes 1 and 2, when a P5PCR bit is set to 1 and the corresponding P5DDR bit is cleared to 0,
the input pull-up transistor is turned on.
The input pull-up transistors are turned off by a reset and in hardware standby mode. In software
standby mode they retain their previous state.
Table 9-5 summarizes the states of the input pull-ups in each mode.

Off: The input pull-up transistor is always off.
On/off: The input pull-up transistor is on if P5PCR = 1 and P5DDR = 0. Otherwise, it is off.
