TXEN
44
Input
Transmit Enable.
In MII mode:
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.
TXER
42
Input
Transmit Error.
When the MAC/Repeater Interface is in:
10M MII mode, TXER is not used.
100M MII mode:
– The ICS1893 synchronously samples its TXER signal on the rising
edges of its TXCLK signal.
– The assertion of TXER by the MAC/repeater causes the ICS1893 to
transmit an Invalid Symbol.
– the Invalid Error Code Test bit (bit 16.2) is set to logic one, the 5-bit
symbol shown in the Invalid Error Code Translation Table (Table
8-17) is used instead of the normal 4B/5B encoding described in the
ISO/IEC specification.
Note: The Invalid Symbol used for this function is the HALT symbol,
which is substituted for the transmit nibble received from the
MAC/repeater whenever the TXER is asserted.
