23.5.19 Capture A

The TCDn.CAPTUREAL and TCDn.CAPTUREAH register pair represents the 12-bit TCDn.CAPTUREA value.

For capture operation, these registers constitute the second buffer level and access point for the CPU. The TCDn.CAPTUREA registers are updated with the buffer value when an update condition occurs. The CAPTURE A register contains the TCD counter value when trigger A or software capture A occurs.

The TCD counter value is synchronized to CAPTUREA by either software or an event.

The capture register is blocked for an update of new capture data until the higher byte of this register is read.
