Timer 3
Timer 3 is a 16-bit timer formed by the two 8-bit SFRs, TMR3L (low byte) and TMR3H (high byte). The input for
Timer 3 is the system clock (divided by either one or twelve as specified by the Timer 3 Clock Select bit T3M in the
Timer 3 Control Register TMR3CN). Timer 3 is always configured as an auto-reload timer, with the reload value
held in the TMR3RLL (low byte) and TMR3RLH (high byte) registers. Timer 3 can be used to start an ADC Data
Conversion, for SMBus timing (see Section 16.5), or as a general-purpose timer. Timer 3 does not have a counter
mode.

Bit7:
TF3: Timer3 Overflow Flag.
Set by hardware when Timer 3 overflows from 0xFFFF to 0x0000. When the Timer 3
interrupt is enabled, setting this bit causes the CPU to vector to the Timer 3 Interrupt
service routine. This bit is not automatically cleared by hardware and must be cleared by
software.
Bits6-3: UNUSED. Read = 0000b, Write = don’t care.
Bit2:
TR3: Timer 3 Run Control.
This bit enables/disables Timer 3.
0: Timer 3 disabled.
1: Timer 3 enabled.
Bit1:
T3M: Timer 3 Clock Select.
This bit controls the division of the system clock supplied to Counter/Timer 3.
0: Counter/Timer 3 uses the system clock divided by 12.
1: Counter/Timer 3 uses the system clock.
Bit0:
UNUSED. Read = 0, Write = don’t care.
