Bit 8 – NODIVCLK No Divided Clock

ValueDescription
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

ValueNameDescription
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

ValueNameDescription
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).
