Description
Reserved
Port addressing error.
An attempt to write to the protected E
occurred.
This bit is set to 1 when a write and subsequent
read from an Optical Module Interface has failed.
This signal should be used to validate the data
being read. Data is only valid if this bit is equal to
zero.
2
Enable the I C block.
2
Start the I C transfer.
Reserved
Bit is asserted when write access is complete.
Reserved
Bit asserted when read access is complete.
Reserved
2
Selects the port for which the I
targeted. Valid range is 0 to 3.
0 = Write transaction
1 = Read transaction
Most-significant four bits of device address field.
Bits 10:8 select the least-significant three bits of
the device address field
Bits 7:0 select the word/register address
Description
Reserved
Bit 23=MSB, Bit 16 = LSB
Data to be written to the Optical Module Interface.
Reserved
Bit 7 = MSB, Bit 0 = LSB
Data read from the Optical Module Interface.
