Bit 8 – NODIVCLK No Divided Clock
| Value | Description |
|---|---|
| 0 | The selected clock is defined by field TCCLKS in TC_CMRx. |
| 1 | The selected clock is peripheral clock and TCCLKS field (TC_CMRx) has no effect. |
Bits 5:4 – TRIGSRCB[1:0] Trigger Source for Input B
| Value | Name | Description |
|---|---|---|
| 0 | EXTERNAL_TIOBx | The trigger/capture input B is driven by external pin TIOBx |
| 1 | PWMx | For TC0, TC1.TIOB0, TC1.TIOB2: The trigger/capture input B is driven internally by the comparator output (see Synchronization with PWM) of the PWMx. |
Bits 1:0 – TRIGSRCA[1:0] Trigger Source for Input A
