SWITCHING PRESCALER ASSIGNMENT
The prescaler assignment is fully under software
control (i.e., it can be changed “on the fly” during
program execution).

TABLE 6-1
REGISTERS ASSOCIATED WITH TIMER0
Note:
To avoid an unintended device RESET, the
following
instruction
sequence
(Example 6-1) must be executed when
changing the prescaler assignment from
Timer0 to the WDT. This sequence must
be taken even if the WDT is disabled. To
change prescaler from the WDT to the
Timer0 module use the sequence shown in
Address
