The Timer0 module incorporates the following features:
• Software-selectable operation as a timer or
• Readable and writable registers
• Dedicated 8-bit, software programmable
• Selectable clock source (internal or external)
• Edge select for external clock
• Interrupt-on-overflow

TMR0ON: Timer0 On/Off Control bit
1 = Enables Timer0
0 = Stops Timer0
T08BIT: Timer0 8-Bit/16-Bit Control bit
1 = Timer0 is configured as an 8-bit timer/counter
0 = Timer0 is configured as a 16-bit timer/counter
T0CS: Timer0 Clock Source Select bit
1 = Transition on T0CKI pin input edge
0 = Internal clock (F
T0SE: Timer0 Source Edge Select bit
1 = Increment on high-to-low transition on the T0CKI pin
0 = Increment on low-to-high transition on the T0CKI pin
PSA: Timer0 Prescaler Assignment bit
1 = Timer0 prescaler is not assigned; Timer0 clock input bypasses the prescaler
0 = Timer0 prescaler is assigned; Timer0 clock input comes from the prescaler output
