MC loop back operation is initiated and enabled by the center MC. The terminal MC provides the loop back path to
return the loop back packet back to the center MC. In terminal MC mode, the KS8993F provides the following loop
back path:
Receive loop back packet from center MC at RXP1/RXM1 input pins of port 1 (fiber).
Turn around loop back packet at MAC of port 2 (copper).
Transmit loop back packet back to center MC from TXP1/TXM1 output pins of port 1 (fiber).

Registers for Media Converter Functions
The KS8993F provides 32 dedicated registers (0x40 to 0x5F) for MC communication between center MC and terminal
MC. Some MC register functions include:
PHY address & configuration
Loop back counters for CRC error, timeout, good packet
Remote commands
Counters for valid MC packet transmitted and received
MC - status, vendor code, and model number
Link Partner - status, vendor code, and model number
