TMSK1 enables OC and IC interrupts. TMSK2 controls pulse accumulator interrupts
and TCNT functions.
OCI[4:1] correspond to OC[4:1].
ICI[3:1] correspond to IC[3:1].
This field selects one of seven prescaler taps or PCLK to be TCNT input.
RESET:
0 = IC4/OC5 interrupt disabled
1 = IC4/OC5 interrupt requested when I4/O5F flag in TFLG1 is set
0 = OC interrupt disabled
1 = OC interrupt requested when OC flag set
0 = IC interrupt disabled
1 = IC interrupt requested when IC flag set
0 = Timer overflow interrupt disabled
1 = Interrupt requested when TOF flag is set
0 = Pulse accumulator overflow interrupt disabled
1 = Interrupt requested when PAOVF flag is set
0 = Pulse accumulator interrupt disabled
1 = Interrupt requested when PAIF flag is set
0 = Normal operation for OC1 pin
1 = TCNT clock driven out OC1 pin
