Timer
TMR0 Prescaler
T0SE
An 8-bit counter is available as a prescaler for the Timer0 module, or as a postscaler for the
Watchdog Timer
the Timer0 description. Thus, a prescaler assignment for the Timer0 module means that there is
no postscaler for the Watchdog Timer, and vice-versa.
The PSA and PS2:PS0 bits (OPTION<3:0>) determine the prescaler assignment and prescale
ratio.
When assigned to the Timer0 module, all instructions writing to the TMR0 register (e.g.,
CLRF TMR0, MOVWF TMR0, BSF TMR0,x....etc.) will clear the prescaler. When assigned to WDT,
a CLRWDT instruction will clear the prescaler along with the Watchdog Timer. The prescaler is not
readable or writable.

There is only one prescaler available which is mutually exclusively shared between
