Collision (Detect).
The ICS1893Y-10 asserts a signal on the COL pin when the ICS1893Y-10
detects receive activity while transmitting (that is, while the TXEN signal is
asserted by the MAC/repeater, that is, when transmitting). When the
mode is:
Carrier Sense.
When the ICS1893Y-10 mode is:
Management Data Clock.
The ICS1893Y-10 uses the signal on the MDC pin to synchronize the
transfer of management information between the ICS1893Y-10 and the
Station Management Entity (STA), using the serial MDIO data line. The
MDC signal is sourced by the STA.
Note:
1. The signal on the COL pin is not synchronous to either RXCLK or
2. In full-duplex mode, the COL signal is disabled and always remains
3. The COL signal is asserted as part of the signal quality error (SQE)

Note: The signal on the CRS pin is not synchronous to the signal on
10Base-T, the ICS1893Y-10 detects receive activity by monitoring the
un-squelched MDI receive signal.
100Base-TX, the ICS1893Y-10 detects receive activity when there are
two non-contiguous zeros in any 10-bit symbol derived from the MDI
receive data stream.
Half-duplex, the ICS1893Y-10 asserts a signal on its CRS pin when it
detects either receive or transmit activity.
Either full-duplex or Repeater mode, the ICS1893Y-10 asserts a signal
on its CRS pin only in response to receive activity.
