8-bit Mode

In this mode Timer0 increments on the rising edge of the selected clock source. A prescaler on the clock input gives several prescale options (see prescaler control bits, T0CKPS).

In this mode as shown in the 8-bit TMR0 Body Diagram, a buffered version of TMR0H is maintained. This is compared with the value of TMR0L on each cycle of the selected clock source. When the two values match, the following events occur:
