Comments

1 = acquisition horizontal sync interrupt request. This bit is set

by the positive edge of HS. It must be reset by software.

1 = enable acquisition horizontal sync interrupt request.

1 = acquisition vertical sync interrupt request. This bit is set by

the positive edge of VS. It must be reset by software.

1 = enable acquisition vertical sync interrupt request.

1 = acquisition line 24 interrupt request. Acquisition hardware

processing in VBI interval is finished. This bit assists the

synchronization of acquisition software to the ACQ-

Timing. It is set by hardware at the beginning of line 24

and the corresponding line of 2nd field. It is reset by

software.

1 = enable acquisition line 24 interrupt request.

1 = even field interrupt. Must be reset by software.

1 = enable even field interrupt requests.
