9.2.4 Input Pull-Up Transistors
Port 4 has built-in MOS input pull-up transistors that can be controlled by software. These input
pull-up transistors can be used in 8-bit bus mode. They can be turned on and off individually.
In 8-bit bus mode, when a P4PCR bit is set to 1 and the corresponding P4DDR 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 9-3 summarizes the states of the input pull-ups in the 8-bit and 16-bit bus modes.

Legend
Off:
On/off: The input pull-up transistor is on if P4PCR = 1 and P4DDR = 0. Otherwise, it is off.
The input pull-up transistor is always off.
