TIMER0 MODULE
The Timer0 module incorporates the following features:
Software selectable operation as a timer or
counter in both 8-bit or 16-bit modes
Readable and writable registers
Dedicated 8-bit, software programmable
prescaler
Selectable clock source (internal or external)
Edge select for external clock
Interrupt-on-overflow
The T0CON register (Register 12-1) controls all
aspects of the module’s operation, including the
prescale selection. It is both readable and writable.
Figure 12-1 provides a simplified block diagram of the
Timer0 module in 8-bit mode. Figure 12-2 provides a
simplified block diagram of the Timer0 module in 16-bit
mode.

bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
TMR0ON:
Timer0 On/Off Control bit
1
= Enables Timer0
0
= Stops Timer0
bit 6
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
bit 5
T0CS
: Timer0 Clock Source Select bit
1
= Transition on T0CKI pin input edge
0
= Internal clock (FOSC/4)
bit 4
T0SE
: Timer0 Source Edge Select bit
1
= Increment on high-to-low transition on T0CKI pin
0
= Increment on low-to-high transition on T0CKI pin
bit 3
PSA
: Timer0 Prescaler Assignment bit
1
= Timer0 prescaler is not assigned. Timer0 clock input bypasses prescaler.
0
= Timer0 prescaler is assigned. Timer0 clock input comes from prescaler output.
