Enhanced Capture Timer
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.
Read or write anytime.

Read or write anytime.
TOI — Timer Overflow Interrupt Enable
0 = Interrupt inhibited
1 = Hardware interrupt requested when TOF flag set
PUPT — Timer Port Pull-Up Resistor Enable
This enable bit controls pull-up resistors on the timer port pins when
the pins are configured as inputs.
0 = Disable pull-up resistor function
1 = Enable pull-up resistor function
RDPT — Timer Port Drive Reduction
This bit reduces the effective output driver size which can reduce
power supply current and generated noise depending upon pin
loading.
0 = Normal output drive capability
1 = Enable output drive reduction function
TCRE — Timer Counter Reset Enable
This bit allows the timer counter to be reset by a successful output
compare 7 event. This mode of operation is similar to an up-counting
modulus counter.
