Note:
Note: Upon Reset, Timer0 is enabled in 8-bit mode with clock input from T0CKI max. prescale.
The PSA multiplexor bit values in Figures 11-1 and
11-2 do not match the text description of the
Timer0 PSA bit in the T0CON register.
The bit values have been corrected by swapping
the values as shown below (correct values are
shown in bold text):
