Alternate Functions of Port C
Table 9-8.
The Port C has an alternate function as the address high byte for the External Memory Interface.
The Port C pins with alternate functions are shown in
Table 9-9.
The alternate pin configuration is as follows:
• A15/CLKO – Port C, Bit 7
A15, External memory interface address 15.
CLKO, Divided System Clock: The divided system clock can be output on the PC7 pin. The
divided system clock will be output if the CKOUT Fuse is programmed, regardless of the
PORTC7 and DDC7 settings. It will also be output during reset.
