Timer control and status
The various functions of the timer are monitored and controlled using the timer control and status
registers described below.
6.2.1
Timer control registers 1 and 2 (TCR1 and TCR2)
The two timer control registers TCR1 and TCR2 ($002C and $002D) are used to enable the input
captures (IC1IE and IC2IE), output compares (OC1IE and OC2E), and timer overow (TOIE)
functions as well as enabling the compare outputs (CO1E and CO2E), selecting input edge
sensitivity (IEDG1 and IEDG2) and levels of output polarity (OLVL1 and OLVL2).
