23.3.3.1 Programmable Output Events

Programmable output event uses the same logic as the input blanking for trigger selection and delay. It is therefore not possible to configure the functionalities independently. If the input blanking functionality is used, the output event cannot be delayed and the trigger used for input blanking will also be used for the output event.

The programmable output events are controlled by the TCDn.DLYCTRL and TCDn.DLYVAL registers. It is possible to delay the output event by 0 to 256 TCD delay clock cycles if the DLYTRIG bits in TCDn.DLYCTRL is set to 0x2. The delayed output event functionality uses the TCD delay clock and counts until the DLYVAL value is reached before the trigger is sent out as an event. The TCD delay clock is a prescaled version of the TCD synchronization clock and the division factor is set by the DLYPRESC bits in the TCDn.DLYCTRL register. The output event will be delayed by TCD clock period x DLYPRESC division factor x DLYVAL.
