Note: The Invalid Symbol used for this function is the HALT symbol,
The ICS1893 samples its TXEN signal to determine when data is
available for transmission. When TXEN is asserted, the ICS1893
begins sampling the data nibbles on the transmit data lines TXD[3:0]
synchronously with TXCLK. The ICS1893 then transmits this data over
the media.
Following the de-assertion of TXEN, the ICS1893 terminates
transmission of nibbles over the media.
