Selected by ICKS1 and ICKS0 in STCR. For details, see section 12.2.4, Timer Control Register (TCR). If the clock input of channel 0 is the TCNT1 overflow signal and that of channel 1 is the TCNT0 compare match signal, no incrementing clock is generated. Do not use this setting. Counter clear 1 and 0 0 Clear is disabled Cleared on compare match A 0 1 1 Cleared on compare match B 0 Cleared on rising edge of external reset input 1 Timer overflow interrupt enable 0 OVF interrupt request (OVI) is disabled 1 OVF interrupt request (OVI) is enabled Compare match interrupt enable A 0 CMFA interrupt request (CMIA) is disabled 1 CMFA interrupt request (CMIA) is enabled Compare Match Interrupt Enable B 0 CMFB interrupt request (CMIB) is disabled 1 CMFB interrupt request (CMIB) is enabled |
