8.6 Timer Control Register
The timer control (TCR) and free-running counter (TMRH, TMRL,
ACRH, and ACRL) registers are the only registers of the 16-bit timer
affected by reset. The output compare port (TCMP) is forced low after
reset and remains low until OLVL is set and a valid output compare
occurs.
ICIE — Input Capture Interrupt Enable
Bit 7, when set, enables input capture interrupts to the CPU. The
interrupt will occur at the same time bit 7 (ICF) in the TSR register is
set.
OCIE — Output Compare Interrupt Enable
Bit 6, when set, enables output compare interrupts to the CPU. The
interrupt will occur at the same time bit 6 (OCF) in the TSR register is
set.
TOIE — Timer Overflow Interrupt Enable
Bit 5, when set, enables timer overflow (rollover) interrupts to the
CPU. The interrupt will occur at the same time bit 5 (TOF) in the TSR
register is set.
IEDG — Input Capture Edge Select
Bit 1 selects which edge of the input capture signal will trigger a
transfer of the contents of the free-running counter registers to the
input capture registers. Clearing this bit will select the falling edge;
setting it selects the rising edge.
OLVL — Output Compare Output Level Select
Bit 0 selects the output level (high or low) that is clocked into the
output compare output latch at the next successful output compare.
