Function
Description
Slave Alias ID
7
Port0/Port1
7-bit Slave Alias ID of the remote Slave 7 attached to the remote Deserializer. The
transaction will be remapped to the address specified in the Slave ID 7 register. A value
of 0 in this field disables access to the remote Slave 7.
If PORT1_SEL is set, this register controls Port 1 Slave Alias.
Reserved.
RX_BKSV0 BKSV0: Value of byte0 of the Receiver KSV.
RX_BKSV1 BKSV1: Value of byte1 of the Receiver KSV.
RX_BKSV2 BKSV2: Value of byte2 of the Receiver KSV.
RX_BKSV3 BKSV3: Value of byte3 of the Receiver KSV.
RX_BKSV4 BKSV4: Value of byte4 of the Receiver KSV.
TX_KSV0
TX_KSV0: Value of byte0 of the Transmitter KSV.
TX_KSV1
TX_KSV1: Value of byte1 of the Transmitter KSV.
TX_KSV2
TX_KSV2: Value of byte2 of the Transmitter KSV.
TX_KSV3
TX_KSV3: Value of byte3 of the Transmitter KSV.
TX_KSV4
TX_KSV4: Value of byte4 of the Transmitter KSV.
Reserved.
Repeater
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.
KSV_FIFO_RD KSV FIFO Ready: Indicates the receiver has built the list of attached KSVs and computed
Y
the verification value V’.
FAST_I2C
Fast I2C: The HDCP Receiver supports fast I2C. Since the I2C is embedded in the serial
data, this bit is not relevant.
Reserved.
FEATURES_1 1.1_Features: The HDCP Receiver supports the Enhanced Encryption Status Signaling
_1
(EESS), Advance Cipher, and Enhanced Link Verification options.
FAST_REAUT Fast Reauthentication: The HDCP Receiver is capable of receiving (unencrypted) video
H
signal during the session re-authentication.
MAX_DEVS_E Maximum Devices Exceeded: Indicates a topology error was detected. Indicates the
XCEEDED
number of downstream devices has exceeded the depth of the Repeater's KSV FIFO.
DEVICE_COU Device Count: Total number of attached downstream device. For a Repeater, this will
NT
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.
