Alternate Functions of Port G

The alternate pin configuration is as follows:

Note:

1. Port G, PG5 is input only. Pull-up is always on.

See Table 26-3 on page 294 for RSTDISBL fuse.

The alternate pin configuration is as follows:

• RESET – Port G, Bit 5

RESET: External Reset input. When the RSTDISBL Fuse is programmed (‘0’), PG5 will function

as input with pull-up always on.

• T0/SEG – Port G, Bit 4

T0, Timer/Counter0 Counter Source.

SEG, LCD front plane 32/23.

• T1/SEG24 – Port G, Bit 3

T1, Timer/Counter1 Counter Source.

SEG, LCD front plane 33/24.
