Description
Compare Match Interrupt Enable B
Selects whether CMFB interrupt requests (CMIB)
are enabled or disabled when the CMFB flag in
TCSR is set to 1.
0: CMFB interrupt requests (CMIB) are disabled
1: CMFB interrupt requests (CMIB) are enabled
Compare Match Interrupt Enable A
Selects whether CMFA interrupt requests (CMIA)
are enabled or disabled when the CMFA flag in
TCSR is set to 1.
0: CMFA interrupt requests (CMIA) are disabled
1: CMFA interrupt requests (CMIA) are enabled
Timer Overflow Interrupt Enable
Selects whether OVF interrupt requests (OVI)
are enabled or disabled when the OVF flag in
TCSR is set to 1.
0: OVF interrupt requests (OVI) are disabled
1: OVF interrupt requests (OVI) are enabled
Counter Clear 1 and 0
These bits select the method by which TCNT is
cleared, in combination with the TMRIS bit in
TCCR. See table 14.2.
Clock Select 2 to 0
These bits select the clock input to TCNT and
the count condition, in combination with the
ICKS1 and ICKS0 bits in TCCR. See table 14.3.
