Output
Input
FCC1: UTOPIA Master Transmit Enable
Asserted by the MSC8101 (UTOPIA master PHY) when there is valid
transmit cell data (TXD[0–7]).
FCC1: UTOPIA Slave Transmit Enable
Asserted by an external UTOPIA master PHY when there is valid
transmit cell data (TXD[0–7]).
FCC1: Media Independent Interface Collision Detect
Asserted by an external fast Ethernet PHY when collision is detected.

Input
FCC1: UTOPIA Slave Transmit Cell Available
Asserted by the MSC8101 (UTOPIA slave PHY) when the MSC8101
can accept one complete ATM cell.
FCC1: UTOPIA Master Transmit Cell Available
Asserted by an external UTOPIA slave PHY to indicate that it can accept
one complete ATM cell.
FCC1: UTOPIA Master Transmit Cell Available Multi-PHY Direct
Polling
Asserted by an external UTOPIA slave PHY using direct polling to
indicate that it can accept one complete ATM cell.
FCC1: Request To Send
In the standard modem interface signals supported by FCC1 (RTS,
CTS, and CD). RTS is asynchronous with the data. RTS is typically used
in conjunction with CD. The MSC8101 FCC1 transmitter requests the
receiver to send data by asserting RTS low. The request is accepted
when CTS is returned low.
FCC1: Media Independent Interface Carrier Sense
Asserted by an external fast Ethernet PHY to indicate activity on the
cable.
PA29
FCC1: TXSOC
UTOPIA master
FCC1: TX_ER
MII
Output
FCC1: UTOPIA Transmit Start of Cell
Asserted by the MSC8101 (UTOPIA master PHY) when TXD[0–7]
contains the first valid byte of the cell.
FCC1: Media Independent Interface Transmit Error
Asserted by the MSC8101 to force propagation of transmit errors.
PA28
FCC1: RXENB
UTOPIA master
FCC1: RXENB
UTOPIA slave
FCC1: TX_EN

Output
FCC1: UTOPIA Master Receive Enable
Asserted by the MSC8101 (UTOPIA master PHY) to indicate that
RXD[0–7] and RXSOC are to be sampled at the end of the next cycle.
RXD[0–7] and RXSOC are enabled only in cycles following those with
RXENB asserted.
FCC1: UTOPIA Master Receive Enable
Asserted by an external PHY to indicate that RXD[0–7] and RXSOC is to
be sampled at the end of the next cycle. RXD[0–7] and RXSOC are
enabled only in cycles following those with RXENB asserted.
FCC1: Media Independent Interface Transmit Enable
Asserted by the MSC8101 when transmitting data.
