Datasheet: ww1.microchip.c...
18F Family Manual: ww1.microchip.c... (See page 109)
Check out the PIC18F4525 playlist on my channel:
• PIC18F4525 Part 001: G...
Also, here are some videos I made looking at the timer registers and interrupt registers. (Mostly, its just me reading the datasheet.):
Timers: • PIC18F4525 Part 016.1:...
Interrupts: • PIC18F4525 Part 016.2:...
These aforementioned vids might be helpful if you are trying to learn.

Timestamps for different prescaler settings (Wow! Fun!): T0C0N = 0x87; setting see at: 6:19 T0C0N = 0x86; setting see at: 7:07 T0C0N = 0x85; setting see at: 8:02 T0C0N = 0x84; setting see at: 8:30 T0C0N = 0x83; setting see at: 9:20 T0C0N = 0x82; setting see at: 10:08 T0C0N = 0x81; setting see at: 10:46 T0C0N = 0x80; not demonstrated on camera, but wowee-wow-wow-fast!
