Pin Functions

The port G pins have only one special function.

8.16.4

MOS Input Pull-Up Function

Port G has a built-in MOS input pull-up function that can be controlled by software. This MOS

input pull-up function can be switched on or off on a bit-by-bit basis.

When a PGDDR bit is cleared to 0, setting the corresponding PGODR bit to 1 will turn on the

MOS input pull-up for that pin.

The MOS input pull-up function is off after a reset and in hardware standby mode. The prior state

is retained when in software standby mode.

Table 8.32 is a summary of the MOS input pull-up states.
