Default Function Descriptions
(hex)
0x00
Reserved
RGB_CHK
SUM_EN
Enable RBG video line checksum.
1: Enables sending of ones-complement checksum for
each 8-bit RBG data channel following end of each
video data line.
0: Checksum disabled
Set via the HDCP_DBG register in the HDCP
Transmitter.
FC_TEST
MODE
Frame Counter Testmode:
1: Speeds up frame counter used for Pj and Ri
verification. When set to a 1, Pj is computed every 2
frames and Ri is computed every 16 frames.
0: Pj is computed every 16 frames and Ri is computed
every 128 frames.
Set via the HDCP_DBG register in the HDCP
Transmitter.
TMR_
SPEEDUP
Timer Speedup:
1: Speed up HDCP authentication timers.
0: Standard authentication timing
Set via the HDCP_DBG register in the HDCP
Transmitter.
HDCP_I2C
_FAST
HDCP I2C Fast mode Enable:
1: Enable the HDCP I2C Master in the HDCP Receiver
to operation with Fast mode timing.
0:Tthe I2C Master will operate with Standard mode
timing.
Set via the HDCP_DBG register in the HDCP
Transmitter.
0x00
Reserved
NO_
DECRYPT
No Decrypt:
1: The HDCP Receiver outputs the encrypted data on
the RGB pins. All other functions will work normally.
This provides a simple way of showing that the link is
encrypted.
0: Normal Operation
Reserved
0x00

RGB_CHK
SUM_ERR
RGB Checksum Error Detected:
If RGB Checksum in enabled through the HDCP
Transmitter HDCP_DBG register, this bit will indicate if
a checksum error is detected. This register may be
cleared by writing any value to this register.
HDCP
Status
HDCP Authenticated:
Indicates the HDCP authentication has completed
successfully. The controller may now send video data
requiring content protection. This bit will be cleared if
authentication is lost or if the controller restarts
authentication.
0x0 HDCP
Serializer Port 0 I2C Address:
Serializer Indicates the I2C address for the Repeater Serializer
Port 0
Port.
Address _{Serializer Port 0 Valid:}
Indicates that the HDCP Repeater has a Serializer port
at the I2C Address identified by upper 7 bits of this
register.
