MOTOROLA
ICIE — Input Capture Interrupt Enable Bit
OCIE — Output Compare Interrupt Enable Bit
TOIE — Timer Overflow Interrupt Enable Bit
IEDG — Input Edge Bit
OLVL — Output Level Bit
Bits 4–2 — Not used; these bits always read 0
This read/write bit enables interrupts caused by an active signal on
the TCAP pin. Reset clears the ICIE bit.
This read/write bit enables interrupts caused by an active signal on
the TCMP pin. Reset clears the OCIE bit.
This read/write bit enables interrupts caused by a timer overflow.
Reset clears the TOIE bit.
The state of this read/write bit determines whether a positive or
negative transition on the TCAP pin triggers a transfer of the contents
of the timer register to the input capture registers. Reset has no effect
on the IEDG bit.
The state of this read/write bit determines whether a logic 1 or a
logic 0 appears on the TCMP pin when a successful output compare
occurs. Reset clears the OLVL bit.
