OM/OL[5:2] — Output Compare Mode Bits and Output Compare Level Bits

Each pair of bits specifies an action to be taken when output comparison is successful.

EDGE[4:1] — Input Capture Edge Control Bits

Each pair of bits configures input sensing logic for the corresponding input capture.

TMSK1 enables OC and IC interrupts. TMSK2 controls pulse accumulator interrupts and TCNT func-

tions.

I4/O5I — Input Capture 4/Output Compare 5 Interrupt Enable

0 = IC4/OC5 interrupt disabled

1 = IC4/OC5 interrupt requested when I4/O5F flag in TFLG1 is set

OCI[4:1] — Output Compare Interrupt Enable

0 = OC interrupt disabled

1 = OC interrupt requested when OC flag set

OCI[4:1] correspond to OC[4:1].

ICI[3:1] — Input Capture Interrupt Enable

0 = IC interrupt disabled

1 = IC interrupt requested when IC flag set

ICI[3:1] correspond to IC[3:1].

TOI — Timer Overflow Interrupt Enable

0 = Timer overflow interrupt disabled

1 = Interrupt requested when TOF flag is set

PAOVI — Pulse Accumulator Overflow Interrupt Enable

0 = Pulse accumulator overflow interrupt disabled

1 = Interrupt requested when PAOVF flag is set

PAII — Pulse Accumulator Input Interrupt Enable

0 = Pulse accumulator interrupt disabled

1 = Interrupt requested when PAIF flag is set

CPROUT — Compare/Capture Unit Clock Output Enable

0 = Normal operation for OC1 pin

1 = TCNT clock driven out OC1 pin

OM/OL[5:2]
