Alternate Functions of Port G
Table 13-20. Overriding Signals for Alternate Functions in PF3:PF0
The alternate pin configuration is as follows:
Table 13-21. Port G Pins Alternate Functions (SEG refers to 100-pin/64-pin pinout)
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/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.
