TOI — Timer Overflow Interrupt Enable
0 = Interrupt inhibited
1 = Hardware interrupt requested when TOF flag set
PUPT — Timer Pull-Up Resistor Enable
This enable bit controls pull-up resistors on the timer port pins when
the pins are configured as inputs.
1 = Enable pull-up resistor function
0 = Disable pull-up resistor function
RDPT — Timer Drive Reduction
This bit reduces the effective output driver size which can reduce
power supply current and generated noise depending upon pin
loading.
1 = Enable output drive reduction function
0 = Normal output drive capability
TCRE — Timer Counter Reset Enable
This bit allows the timer counter to be reset by a successful output
compare 7 event.
0 = Counter reset inhibited and counter free runs
1 = Counter reset by a successful output compare 7
If TC7 = $0000 and TCRE = 1, TCNT will stay at $0000 continuously.
If TC7 = $FFFF and TCRE = 1, TOF will never get set even though
TCNT will count from $0000 through $FFFF.
PR2, PR1, PR0 — Timer Prescaler Select
These three bits specify the number of ÷2 stages that are to be
inserted between the module clock and the timer counter.
