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.
00: Clearing is disabled
01: Clear by compare match A
10: Clear by compare match B
11: Clear by rising edge of external reset input
Clock Select 2 to 0
These bits select the clock input to TCNT and
count condition. See table 13.2.
