PRODUCTION DATA
Reverse Loopback receives data on the MDI and passes it through the entire receive block where it is then looped back within the PCS layer to the transmit block. The data is transmitted back out on the MDI to the attached Link Partner. To avoid contention, MAC transmit path is isolated.
Write register 0x0016 = 0x0110
Use the following register settings to enable checker depending on the MAC interface mode.
Data can also be checked internally by reading registers 0x063C, 0x063D, 0x063E
Write register 0x0619 = 0x0557
Write register 0x0624 = 0x55BF
Data generate by the internal PRBS will be transmitted over the MDI and the MAC interface.
