The bits in TMSK1 correspond bit-for-bit with the bits in the TFLG1 status register.
If cleared, the corresponding flag is disabled from causing a hardware interrupt. If
set, the corresponding flag is enabled to cause a hardware interrupt.

TOI — Timer Overflow Interrupt Enable Bit
PUPT — Timer Pullup Resistor Enable Bit
RDPT — Timer Drive Reduction Bit
Address: $008C
Address: $008D
This enable bit controls pullup resistors on the timer port pins when the pins are
configured as inputs.
This bit reduces the effective output driver size which can reduce power supply
current and generated noise depending upon pin loading.

0 = Interrupt inhibited
1 = Hardware interrupt requested when TOF flag set
0 = Disable pullup resistor function
1 = Enable pullup resistor function
0 = Normal output drive capability
1 = Enable output drive reduction function
