Note:
Note: Upon Reset, Timer0 is enabled in 8-bit mode with clock input from T0CKI max. prescale.
In Figure 11-1 and Figure 11-2 of the Device Data
Sheet, the Timer0 Prescaler Assignment (PSA)
bits are incorrectly stated. To remedy this, the bit
values have been swapped as shown in the
figures below.
