TXEN
44
Input
Transmit Enable.
The signal on this pin indicates to the ICS1892 that the MAC/repeater is
sending valid data nibbles for transmission on the physical media.
Synchronous with the assertion of TXEN, the ICS1892 begins reading
the data nibbles on the transmit data lines and transmitting them over
the media.
Following the de-assertion of TXEN, the ICS1892 terminates
transmission of nibbles.
TXER
42
Input
Transmit Error.
When the mode is:
10Base-T, TXER is not required.
100Base-TX mode:
– The assertion of TXER by the MAC/repeater causes the ICS1892 to
transmit Invalid Symbols. (The ICS1892 synchronously samples the
TXER signal on the rising edges of TXCLK.)
– The Invalid Symbol used for this function is the HALT symbol, which
is substituted for the transmit nibble received from the
MAC/repeater.
– When 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.
