IE IND ACC Interrupt on Indirect Access Complete
Enables interrupt on completion of Indirect Register
Access
IE RXDET
INT
Interrupt on Receiver Detect
Enables interrupt on detection of a downstream
Receiver. If HDCP_CFG:RX_DET_SEL is set to a 1,
the interrupt will wait for Receiver Lock Detect.
IS_RX_INT
Interrupt on Receiver interrupt
Enables interrupt on indication from the HDCP
Receiver. Allows propagation of interrupts from
downstream devices
IE LIST
RDY
Interrupt on KSV List Ready
Enables interrupt on KSV List Ready
IE KSV
RDY
Interrupt on KSV Ready
Enables interrupt on KSV Ready
IE AUTH
FAIL
Interrupt on Authentication Failure
Enables interrupt on authentication failure or loss of
authentication
IE AUTH
PASS
Interrupt on Authentication Pass
Enables interrupt on successful completion of
authentication
INT Enable Global Interrupt Enable
Enables interrupt on the interrupt signal to the
controller.
IS IND ACC Interrupt on Indirect Access Complete
Indirect Register Access has completed
INT Detect Interrupt on Receiver Detect interrupt
A downstream receiver has been detected
IS RX INT
Interrupt on Receiver interrupt
Receiver has indicated an interrupt request from
down-stream device
IS LIST
RDY
Interrupt on KSV List Ready
The KSV list is ready for reading by the controller
IS KSV
RDY
Interrupt on KSV Ready
The Receiver KSV is ready for reading by the
controller
IS AUTH
FAIL
Interrupt on Authentication Failure
Authentication failure or loss of authentication has
occurred
IS AUTH
PASS
Interrupt on Authentication Pass
Authentication has completed successfully
INT
Global Interrupt
Set if any enabled interrupt is indicated
ID0
First byte ID code, ‘_’
ID1
Second byte of ID code, ‘U’
ID2
Third byte of ID code. Value will be either ‘B’ or ‘H’.
‘H’ indicates an HDCP capable device
ID3
Forth byte of ID code: ‘9’
ID4
Fifth byte of ID code: '2'
ID5
Sixth byte of ID code: '5'
