Loopback Support
The KSZ8841M provides Near-end (Remote) loopback support for remote diagnostic of failure. In loopback mode, the
speed at the PHY port will be set to 100BASE-TX full-duplex mode.
Near-end (Remote) Loopback
Near-end (Remote) loopback is conducted at PHY port 1of the KSZ8841M. The loopback path starts at the PHY port’s
receive inputs (RXP1/RXM1), wraps around at the same PHY port’s PMD/PMA, and ends at the PHY port’s transmit
outputs (TXP1/TXM1).
Bit [1] of register P1PHYCTRL is used to enable near-end loopback for port 1. Alternatively, Bit [9] of register P1SCSLMD
can also be used to enable near-end loopback. The ports 1 near-end loopback path is illustrated in the following Figure
