Default Description
1:Enabled : When enabled this register overrides the
clock to PLL mode (External Oscillator mode or Direct
PCLK mode) defined through MODE pin and allows
RW
0
selection through register 0x35 in the Serializer.
0: Disabled : When disabled, Clock to PLL mode
(External Oscillator mode or Direct PCLK mode) is
defined through MODE pin on the Serializer.
Pixel Clock Edge Select.
1: Parallel Interface Data is strobed on the Rising
RW
1
Clock Edge.
0: Parallel Interface Data is strobed on the Falling
Clock Edge.

channel.
1: Overrides MODE select bits.
0: Does not override MODE select bits.
1: Status of mode select from Deserializer is up-to-
R
0
date.
0: Status is NOT up-to-date.

1: 12-bit high frequency mode is selected.

1: 10-bit mode is selected.
0: 10-bit mode is not selected.

7-bit Deserializer Device ID Configures the I2C Slave
ID of the remote Deserializer. A value of 0 in this field
disables I2C access to the remote Deserializer. This
RW
0x00'h
field is automatically configured by the Bidirectional
Control Channel once RX Lock has been detected.
Software may overwrite this value, but should also
assert the FREEZE DEVICE ID bit to prevent
overwriting by the Bidirectional Control Channel.
1: Prevents auto-loading of the Deserializer Device ID
RW
0
by the bidirectional control channel. The ID will be
frozen at the value written.
0: Update.
7-bit Remote Deserializer Device Alias ID Configures
the decoder for detecting transactions designated for
an I2C Deserializer device. The transaction will be
RW
0x00'h remapped to the address specified in the DES ID
register.
A value of 0 in this field disables access to the remote
Deserializer.
Reserved.
7-bit Remote Slave Device ID Configures the physical
I2C address of the remote I2C Slave device attached
to the remote Deserializer. If an I2C transaction is
RW
0x00'h
addressed to the Slave Alias ID, the transaction will be
remapped to this address before passing the
transaction across the Bidirectional Control Channel to
the Deserializer and then to remote slave. A value of
0 in this field disables access to the remote I2C slave.
