Section 8 I/O Ports
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 1, 2, 3, 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 a PADDR bit is cleared to 0, setting the corresponding PAPCR bit to 1 turns on the MOS
input pull-up for that pin.
The MOS input pull-up function is in the off state after a power-on reset, and in hardware standby
mode. The prior state is retained after a manual reset, and in software standby mode.
Table 8.10 summarizes the MOS input pull-up states.
