Function Description
159 0x9F TX_AN7 7:0 R 0x00 TX AN7 TX_AN7: Value of byte 7 of the Serializer AN
Value
160 0xA0 RX BCAPS 7 0x00
Reserved
6 R Repeater Indicates if the attached Receiver supports
downstream connections. This bit is valid once the
Bksv is ready as indicated by the BKSV_RDY bit
in the HDCP
5 R KSV FIFO KSV FIFO Ready
Indicates the receiver has built the list of attached
KSVs and computed the verification value
4:2 Reserved
1 R Features HDCP v1.1_Features
The HDCP Receiver supports the Enhanced
Encryption Status Signaling (EESS), Advance
Cipher, and Enhanced Link Verification options.
0 R Fast Re-
auth The HDCP Receiver is capable of receiving
(unencrypted) video signal during the session re-
authentication.
161 0xA1 RX
BSTATUS0 7 R 0x00 Max
Devices Maximum Devices Exceeded: Indicates a
topology error was detected. Indicates the number
of downstream devices has exceeded the depth of
the Repeater's KSV FIFO
6:0 R Device
Count Total number of attached downstream device. For
a Repeater, this will indicate the number of
downstream devices, not including the Repeater.
For an HDCP Receiver that is not also a Repeater,
this field will be 0
162 0xA2 RX
BSTATUS1 7:4 0x00 Reserved
3 R Max
Cascade Maximum Cascade Exceeded: Indicates a
topology error was detected — more than seven
levels of repeaters have been cascaded together
2:0 R Cascade
Depth Indicates the number of attached levels of devices
for the Repeater
163 0xA3 KSV FIFO 7:0 R 0x00 KSV FIFO KSV FIFO
Each read of the KSV FIFO returns one byte of the
KSV FIFO list composed by the downstream
Receiver.
