Description
PG Indirect Data
When writing to indirect registers, this register contains the data to be
written. When reading from indirect registers, this register contains the
read back value.
See TI App Note AN-2198
Slave ID 1
Port0/Port1
7-bit I2C address of the remote Slave 1 attached to the remote
Deserializer. If an I2C transaction is addressed to Slave Alias ID 1, the
transaction will be remapped to this address before passing the
transaction across the Bidirectional Control Channel to the
Deserializer. A value of 0 in this field disables access to the remote
Slave 1.
If Port1_SEL is set, this register controls Port1 operation.
Reserved.
Slave ID 2
Port0/Port1
7-bit I2C address of the remote Slave 2 attached to the remote
Deserializer. If an I2C transaction is addressed to Slave Alias ID 2, the
transaction will be remapped to this address before passing the
transaction across the Bidirectional Control Channel to the
Deserializer. A value of 0 in this field disables access to the remote
Slave 2.
If Port1_SEL is set, this register controls Port1 operation.
Reserved.
Slave ID 3
Port0/Port1
7-bit I2C address of the remote Slave 3 attached to the remote
Deserializer. If an I2C transaction is addressed to Slave Alias ID 3, the
transaction will be remapped to this address before passing the
transaction across the Bidirectional Control Channel to the
Deserializer. A value of 0 in this field disables access to the remote
Slave 3.
If Port1_SEL is set, this register controls Port1 operation.
Reserved.
Slave ID 4
Port0/Port1
7-bit I2C address of the remote Slave 4 attached to the remote
Deserializer. If an I2C transaction is addressed to Slave Alias ID 4, the
transaction will be remapped to this address before passing the
transaction across the Bidirectional Control Channel to the
Deserializer. A value of 0 in this field disables access to the remote
Slave 4.
If Port1_SEL is set, this register controls Port1 operation.
Reserved.
