An 8-bit counter is available as a prescaler for the
Timer0 module, or as a postscaler for the Watchdog
Timer, respectively (Figure 6-6). For simplicity, this
counter is being referred to as “prescaler” throughout
this data sheet. Note that there is only one prescaler
available which is mutually exclusively shared between
the Timer0 module and the Watchdog Timer. Thus, a
prescaler assignment for the Timer0 module means
that there is no prescaler for the Watchdog Timer, and
vice-versa.
The PSA and PS2:PS0 bits (OPTION<3:0>) determine
the prescaler assignment and prescale ratio.
Prescaler
When assigned to the Timer0 module, all instructions
writing to the TMR0 register (e.g.
CLRF 1, MOVWF 1,
BSF
1,x
....etc.) will clear the prescaler. When
assigned to WDT, a
CLRWDT
instruction will clear the
prescaler along with the Watchdog Timer. The pres-
caler is not readable or writable.
Note:
Writing to TMR0 when the prescaler is
assigned to Timer0 will clear the prescaler
count, but will not change the prescaler
assignment.
