Pull-Up MOS Transistor Control:
A program-controlled pull-up MOS transistor is provided for each
input/output pin other than input-only pins D
10
and D
11
. The on/off status of all these transistors is
controlled by bit 3 (MIS3) of the miscellaneous register (MIS: $00C), and the on/off status of an individual
transistor can also be controlled by the port data register (PDR) of the corresponding pin—enabling on/off
control of that pin alone (table 23 and figure 38).
The on/off status of each transistor and the peripheral function mode of each pin can be set independently.
