Bit 7 – DISEOC Disable at End of TCD Cycle Strobe

When this bit is written, the TCD will automatically disable at the end of the TCD cycle.

When this bit is written to ‘1’, the ENRDY in TCDn.STATUS will keep low until the TCD is disabled.

Writing to this bit only has effect if there is no ongoing synchronization of Enable. See also ENRDY bit in TCDn.STATUS.

Bit 4 – SCAPTUREB Software Capture B Strobe

When this bit is written to ‘1’, a software capture to Capture register B (TCDn.CAPTUREBL/H) is done as soon as the strobe is synchronized to the TCD domain.

Writing to this bit only has effect if there is no ongoing synchronization of a command. See also CMDRDY bit in TCDn.STATUS.

Bit 3 – SCAPTUREA Software Capture A Strobe

When this bit is written to ‘1’, a software capture to Capture register A (TCDn.CAPTUREAL/H) is done as soon as the strobe is synchronized to the TCD domain.

Writing to this bit only has effect if there is no ongoing synchronization of a command. See also CMDRDY bit in TCDn.STATUS.

Bit 2 – RESTART Restart Strobe

When this bit is written a restart of the TCD counter is executed as soon as this bit is synchronized to the TCD domain.

Writing to this bit only has effect if there is no ongoing synchronization of a command. See also CMDRDY bit in TCDn.STATUS.

Bit 1 – SYNC Synchronize Strobe

When this bit is written to ‘1’ the double buffered registers will be loaded to the TCD domain as soon as this bit is synchronized to the TCD domain.

Writing to this bit only has effect if there is no ongoing synchronization of a command. See also CMDRDY bit in TCDn.STATUS.

Bit 0 – SYNCEOC Synchronize End of TCD Cycle Strobe

When this bit is written to ‘1’ the double buffered registers will be loaded to the TCD domain at the end of the next TCD cycle.

Writing to this bit only has effect if there is no ongoing synchronization of a command. See also CMDRDY bit in TCDn.STATUS.
