How to get the PIC18F6720 in µC mode (CCP2 on RE7)
PostPosted: Sat Jun 12, 2004 6:17 am     Reply with quote
I use the PWM module over CCP2. THe pin is multiplexed with RC1 and RE7 in "microcontroller mode" and multiplexed with RC1 and RB3 depending on witch mode the PIC is running. The mode can be set in the control register "CONFIG3L". To set the MUX bit the fuses "CCP2E7" and "CCP2C1" can be used. but I didn't found any fuse to bring the controller in microcontroller mode.
If there is no fuse for that, how can I directly acces to that configuration register?

Thx for help

If you look at the data sheet for the XX20 chips, the external memory bus (microcontroller mode), is only available on the 8x20 chips, not the 6x20. Hence the lack of this fuse in your chip....

Best Wishes
