Bit [8] of registers P1CR4 and P2CR4 is used to enable far-end loop back for ports 1 and 2, respectively. Alternatively,
Bit [14] of registers P1MBCR and P2MBCR can also be used to enable far-end loop back. When register P2MBCR bit
14 =1 or P2CR4 bit 8 =1, the port 2 far-end loop back path is illustrated in the Figure 11.
Near-end (Remote) Loop back:
Near-end (Remote) loop back is conducted at either PHY port 1 or PHY port 2 of the KSZ8842-PMQL/PMBL. The loop
back path starts at the PHY port’s receive inputs (RXPx/RXMx), wraps around at the same PHY port’s PMD/PMA, and
ends at the PHY port’s transmit outputs (TXPx/TXMx).
Bit [1] of registers P1PHYCTRL and P2PHYCTRL is used to enable near-end loop back for ports 1 and 2, respectively.
Alternatively, Bit [9] of registers P1SCSLMD and P2SCSLMD can also be used to enable near-end loop back. Both
ports 1 and 2 near-end loop back paths are illustrated in the following Figure 10.
