Section 8 I/O Ports
Note: * Modes 6 and 7 are not available in the ROMless versions.
8.6.4
Port A has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be used in modes 6 and 7 * , and cannot be used in modes 4 and 5. MOS
input pull-up can be specified as on or off on an individual bit basis.
When PADDR bits are cleared to 0, setting the corresponding PAPCR bits to 1 turns on the MOS
input pull-up for that pins.
The MOS input pull-up function is in the off state after a reset, and in hardware standby mode.
The prior state is retained in software standby mode.
Table 8.10 summarizes the MOS input pull-up states.

4, 5
Legend:
OFF:
ON/OFF: On when PADDR = 0 and PAPCR = 1; otherwise off.
Note: * Modes 6 and 7 are not available in the ROMless versions.
