Timer Control
Register
15-tim1ic1oc_a
MOTOROLA
The timer control register (TCR) performs the following functions:
ICIE — Input Capture Interrupt Enable
OCIE — Output Compare Interrupt Enable
TOIE — Timer Overflow Interrupt Enable
Bits 4–2 — Unused

This read/write bit enables interrupts caused by an active signal on
the PD7/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.
These are read/write bits that always read as logic 0s.
