Note
: Once TXEN is cleared, the last symbol gets encoded and transmitted, the looped-back data is presented
back to the MAC, and RXCRS falls. Once RXCRS falls, TXCLK and RXCLK toggle for 96 clocks, after which
the system returns to the Idle state.

CLS
Note: CLS will be asserted some time after the preamble and SFD have been clocked in. TXCLK and RXCLK
are then clocked until RXCRS drops. TXEN drops about 32 clocks after CLS was asserted. RXCRS and CLS
are dropped together after more than 500 clocks (about 120
μ
s). TXCLK and RXCLK keep toggling for approx-
imately another 100 clock cycles, when the system returns to the Idle state.
