Bit | field (1) | symval (1) | Value | Description |
23 | LFDB | OF(value) |
| Long field detected on channel B interrupt detected bit. (A long field is only detected |
|
|
|
| when the VRST bit in VCBCTL is cleared to 0; when VRST = 1, a long field is always |
|
|
|
| detected.) |
|
|
|
| BT.656 or Y/C capture mode - LFDB is set when long field detection is enabled and |
|
|
|
| VCOUNT is not reset before VCOUNT = YSTOP + 1. |
|
|
|
| Raw data mode, or TCI capture mode or display mode - Not used. |
|
| DEFAULT | 0 | No interrupt is detected. |
|
| NONE |
|
|
|
| CLEAR | 1 | Interrupt is detected. Bit is cleared. |
22 | SFDB | OF(value) |
| Short field detected on channel B interrupt detected bit. |
|
|
|
| BT.656 or Y/C capture mode - SFDB is set when short field detection is enabled and |
|
|
|
| VCOUNT is reset before VCOUNT = YSTOP. |
|
|
|
| Raw data mode, or TCI capture mode or display mode - Not used. |
|
| DEFAULT | 0 | No interrupt is detected. |
|
| NONE |
|
|
|
| CLEAR | 1 | Interrupt is detected. Bit is cleared. |
21 | VINTB2 | OF(value) |
| Channel B field 2 vertical interrupt detected bit. |
|
|
|
| BT.656 or Y/C capture mode - VINTB2 is set when a vertical interrupt occurred in field |
|
|
|
| 2. |
|
|
|
| Raw data mode or TCI capture mode - Not used. |
|
| DEFAULT | 0 | No interrupt is detected. |
|
| NONE |
|
|
|
| CLEAR | 1 | Interrupt is detected. Bit is cleared. |
20 | VINTB1 | OF(value) |
| Channel B field 1 vertical interrupt detected bit. |
|
|
|
| BT.656 or Y/C capture mode - VINTB1 is set when a vertical interrupt occurred in field |
|
|
|
| 1. |
|
|
|
| Raw data mode or TCI capture mode - Not used. |
|
| DEFAULT | 0 | No interrupt is detected. |
|
| NONE |
|
|
|
| CLEAR | 1 | Interrupt is detected. Bit is cleared. |
19 | SERRB | OF(value) |
| Channel B synchronization error interrupt detected bit. |
|
|
|
| BT.656 or Y/C capture mode - Synchronization parity error on channel B. An SERRB |
|
|
|
| typically requires resetting the channel (RSTCH) or the port (VPRST). |
|
|
|
| Raw data mode or TCI capture mode - Not used. |
|
| DEFAULT | 0 | No interrupt is detected. |
|
| NONE |
|
|
|
| CLEAR | 1 | Interrupt is detected. Bit is cleared. |
18 | CCMPB | OF(value) |
| Capture complete on channel B interrupt detected bit. (Data is not in memory until the |
|
|
|
| EDMA transfer is complete.) |
|
|
|
| BT.656 or Y/C capture mode - CCMPB is set after capturing an entire field or frame |
|
|
|
| (when F1C, F2C, or FRMC in VCBSTAT are set) depending on the CON, FRAME, |
|
|
|
| CF1, and CF2 control bits in VCBCTL. |
|
|
|
| Raw data mode - RDFE is not set, CCMPB is set when FRMC in VCBSTAT is set |
|
|
|
| (when the data counter = the combined VCYSTOP/VCXSTOP value). |
|
|
|
| TCI capture mode - CCMPB is set when FRMC in VCBSTAT is set (when the data |
|
|
|
| counter = the combined VCYSTOP/VCXSTOP value). |
|
| DEFAULT | 0 | No interrupt is detected. |
|
| NONE |
|
|
|
| CLEAR | 1 | Interrupt is detected. Bit is cleared. |
