TIMER CONTROL REGISTER (TCR)
The timer control register is shown in Figure 9-12 performs the following func-
tions:
Enables input capture interrupts
Enables output compare interrupts
Enables timer overow interrupts
Control the active edge polarity of the TCAP signal on pin PB0/TCAP
Reset clears all the bits in the TCR with the exception of the IEDG bit which is
unaffected.
ICIE - INPUT CAPTURE INTERRUPT ENABLE
This read/write bit enables interrupts caused by an active signal on the PB0/
TCAP pin. Reset clears the ICIE bit.
1 =
Input capture interrupts enabled.
0 =
Input capture interrupts disabled.
OCIE - OUTPUT COMPARE INTERRUPT ENABLE
This read/write bit enables interrupts caused by a successful compare between
the timer counter and the output compare registers. Reset clears the OCIE bit.
1 =
Output compare interrupts enabled.
0 =
Output compare interrupts disabled.
TOIE - TIMER OVERFLOW INTERRUPT ENABLE
This read/write bit enables interrupts caused by a timer overow. Reset clears
the TOIE bit.
1 =
Timer overow interrupts enabled.
0 =
Timer overow interrupts disabled.
