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 all channels: 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
Value | Name | Description |
---|---|---|
0 | EXTERNAL_TIOAx |
The trigger/capture input A is driven by external pin TIOAx |
1 | PWMx |
For TC0, TC1.TIOA0, TC1.TIOA2: The trigger/capture input A is driven internally by PWMx. For TC1.TIOA1: The trigger/capture input A is driven internally by the GTSUCOMP signal of the Ethernet MAC (GMAC). |
