Pin Description
Digital Video Input Pins
Pin Name Direction Description
D[23:0]
Input
Digital video input pins. D[23:12] are only used in 24-bit
single-edged mode. In 12-bit, dual-edged mode D[23:12] should
be tied to ground.

2. Receiver detection circuit reports the presence or absence of an active termination at the TMDS
Clock Channel (Register 0Eh[5], RxSENDetect)
3. DDC bus is hanged for any reasons
4. Audio FIFO overflows
5. HDCP authentication fails
6. Video data is stable or not
A typical initialization of HDMI link should be based on interrupt signal and appropriate register probing.
Recommended flow is detailed in CAT6612 Programming Guide. Simply put, the microcontroller
should monitor the HPD status first. Upon valid HPD event, move on to check RxSENDetect register
to see if the receiver chip is ready for further handshaking. When RxSENDetect is asserted, start
reading EDID data through DDC channels and carry on the rest of the handshaking subsequently.
If the micro-controller makes no use of the interrupt signal as well as the above-mentioned status
registers, the link establishment might fail. Please do follow the suggested initialization flow
recommended in CAT6612 Programming Guide.
