Alternate Functions of Port G
Table 14-13. Overriding Signals for Alternate Functions in PF3:PF0
The alternate pin configuration is as follows:
Table 14-14. Port G Pins Alternate Functions
Note:
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 – Port G, Bit 4
T0, Timer/Counter0 Counter Source.
• T1 – Port G, Bit 3
T1, Timer/Counter1 Counter Source.
