6.2
The various functions of the timer are monitored and controlled using the timer control and status
registers described below.
6.2.1
The timer control register ($0012) is used to enable the input captures (ICIE), output compares
(OCIE), and timer overflow (TOIE) functions as well as forcing output compares (FOLV1 and
FOLV2), selecting input edge sensitivity (IEDG1) and levels of output polarity (OLV1 and OLV2).
ICIE — Input captures interrupt enable
If this bit is set, a timer interrupt is enabled whenever the ICF1 or ICF2 status flag (in the timer
status register) is set.
OCIE — Output compares interrupt enable
If this bit is set, a timer interrupt is enabled whenever the OCF1 or OCF2 status flag (in the timer
status register) is set.
TOIE — Timer overflow interrupt enable
If this bit is set, a timer interrupt is enabled whenever the TOF status flag (in the timer status
register) is set.
