Pull-Up MOS Control
Program-controllable pull-ups MOS are incorporated in all I/O pins.
On/off control of all pull-ups MOS is performed by bit 3 (MIS3) of the miscellaneous register (MIS: $005)
and the port data register (PDR) for each pin, enabling the pull-up MOS to be turned on or off
independently for each pin (table 22, figure 30).
Except for analog input multiplexed pins, the pull-up MOS on/off setting can be made independent of the
setting as an on-chip supporting module pin.
