MOD=TIMER_MODE_THE_TC_I, CIS=FOR_PWM0_00_EQ_PWM0_
Count Control Register. The CTCR selects between Timer and Counter mode, and in Counter mode selects the signal and edge(s) for counting.
| MOD | Counter/ Timer Mode 0 (TIMER_MODE_THE_TC_I): Timer Mode: the TC is incremented when the Prescale Counter matches the Prescale register. 1 (RISING_EDGE_COUNTER_): Rising edge counter Mode: the TC is incremented on rising edges of the PWM_CAP input selected by bits 3:2. 2 (FALLING_EDGE_COUNTER): Falling edge counter Mode: the TC is incremented on falling edges of the PWM_CAP input selected by bits 3:2. 3 (DUAL_EDGE_COUNTER_MO): Dual edge counter Mode: the TC is incremented on both edges of the PWM_CAP input selected by bits 3:2. |
| CIS | Count Input Select. When bits 1:0 are not 00, these bits select which PWM_CAP pin carries the signal used to increment the TC. Other combinations are reserved. 0 (FOR_PWM0_00_EQ_PWM0_): For PWM0: 00 = PWM0_CAP0 (Other combinations are reserved) For PWM1: 00 = PWM1_CAP0, 01 = PWM1_CAP1 (Other combinations are reserved) |
| RESERVED | Reserved. Read value is undefined, only zero should be written. |
