Selects whether the CMFB interrupt request (CMIB) is
enabled or disabled when the CMFB flag in TCSR is set to
1. Note that a CMIB interrupt is not generated by TMR_X,
regardless of the CMIEB value.
0: CMFB interrupt request (CMIB) is disabled
1: CMFB interrupt request (CMIB) is enabled
Selects whether the CMFA interrupt request (CMIA) is
enabled or disabled when the CMFA flag in TCSR is set to
1. Note that a CMIA interrupt is not generated by TMR_X,
regardless of the CMIEA value.
0: CMFA interrupt request (CMIA) is disabled
1: CMFA interrupt request (CMIA) is enabled
Selects whether the OVF interrupt request (OVI) is enabled
or disabled when the OVF flag in TCSR is set to 1. Note
that an OVI interrupt is not generated by TMR_X,
regardless of the OVIE value.
0: OVF interrupt request (OVI) is disabled
1: OVF interrupt request (OVI) is enabled
Counter Clear 1, 0
These bits select the method by which the timer counter is
cleared.
00: Clearing is disabled
01: Cleared on compare-match A
10: Cleared on compare-match B
11: Cleared on rising edge of external reset input
Clock Select 2 to 0
These bits select the clock input to TCNT and count
condition, together with the ICKS1 and ICKS0 bits in STCR.
