The Video Register Map is always active, whether valid serial input data is present or not. 4.21.1 Video Core Registers Table 4-27:Video Core Configuration and Status Registers Address Register Name Bit Name Bit Description R/W Default 000h IOPROC_1 RSVD 15 Reserved. R 0 TRS_WORD_REMAP_DS1 _DISABLE 14 Disables 8-bit TRS word remapping for 3G Level B Data Stream 1, 3G Level A, HD and SD inputs. R/W 0 RSVD 13 Reserved. R/W 0 EDH_FLAG_UPDATE _MASK 12 Disables updating of EDH error flags. R/W 0 EDH_CRC_INS_MASK11 Disables EDH_CRC error correction and insertion. R/W 0 H_CONFIG 10 Selects the H blanking indication: 0: Active line blanking - the H output is HIGH for all the horizontal blanking period, including the EAV and SAV TRS words. 1: TRS based blanking - the H output is set HIGH for the entire horizontal blanking period as indicated by the H bit in the received TRS signals. This signal is only valid when TIM_861 is set to '0' (via pin or host interface). R/W 0 ANC_DATA_EXT_MASK9 Disables ancillary data extraction FIFO. R/W 0 AUD_EXT_MASK8 Disables audio extraction block. R/W 0 TIM_861_PIN_DISABLE 7 Disable TIM_861 pin control when set to '1', and use TIMING_861 bit instead. R/W 0 TIMING_861 6Selects the output timing reference format: 0 = Digital FVH timing output; 1 = CEA-861 timing output. R/W 0 RSVD 5 Reserved. R/W 0 ILLEGAL_WORD_REMAP _DS1_MASK 4Disables illegal word remapping for 3G Level B Data Stream 1, 3G Level A, HD and SD inputs. R/W 0 |
