T echo
RN1B [0d27, 0x1B]: Auxiliary mode 2 register
Block 10BaseT echo: Default 0. When enabled during 10BASE-T half-duplex transmit
operation, the TXEN signal does not echo onto the RXDV pin. The TXEN echoes onto the
CRS pin, and the CRS de-assertion directly follows the TXEN de-assertion.
SQE disable: Default 0. When asserted, it disables SQE pulses when operating in 10BASE-
T half-duplex mode.
