SNLS589B September 2016 – July 2018 DS90UB960-Q1
The DS90UB960-Q1 is able to monitor and detect several other RX port specific conditions and interrupt states. This information is latched into the RX port status registers RX_PORT_STS1 0x4D (See Table 94) and RX_PORT_STS2 0x4E (See Table 95). There are bits to flag any change in LOCK status (LOCK_STS_CHG) or detect any errors in the control channel over the forward link (BCC_CRC_ERROR, BCC_SEQ_ERROR) which are cleared upon read. The Rx Port status registers also allow monitoring of the presence stable input signal along with monitoring parity and CRC errors, line length and lines per video frame.
