Note: The Invalid Symbol used for this function is the HALT symbol,
The ICS1893Y-10 samples its TXEN signal to determine when data is
available for transmission. When TXEN is asserted, the ICS1893Y-10
begins sampling the data nibbles on the transmit data lines TXD[3:0]
synchronously with TXCLK. The ICS1893Y-10 then transmits this data
over the media.
Following the de-assertion of TXEN, the ICS1893Y-10 terminates
transmission of nibbles over the media.
