Port B Signals
PA7
SMC2: SMSYN
SI1 TDMA1: L1TSYNC
TDM nibble and TDM serial
Input
SMC2: Serial Management Synchronization
The SMC interface consists of SMTXD, SMRXD, SMSYN, and a clock.
Not all signals are used for all applications. SMCs are full-duplex ports
that supports three protocols or modes: UART, transparent, or general-
circuit interface (GCI).
Time-Division Multiplexing A1: Layer 1 Transmit Synchronization
The synchronizing signal for the transmit channel. See the
Serial
Interface with time-slot assigner chapter in the MSC8101 Reference
Manual.
PA6
SI1 TDMA1: L1RSYNC
TDM nibble and TDM serial
Input
Time-Division Multiplexing A1: Layer 1 Receive Synchronization.
The synchronizing signal for the receive channel.

FCC2: Media Independent Interface Transmit Error
Asserted by the MSC8101 to force propagation of transmit errors.
SCC2: Receive Data
SCC2 receives serial data from RXD.
Time-Division Multiplexing B2: Layer 1 Transmit Data
TDMB2 transmits serial data out of L1TXD.

SCC2: Transmit Data.
SCC2 transmits serial data out of TXD.
FCC2: Media Independent Interface Receive Data Valid
Asserted by an external fast Ethernet PHY to indicate that valid data is
being sent. The presence of carrier sense, but not RX_DV, indicates
reception of broken packet headers, probably due to bad wiring or a bad
circuit.
Time-Division Multiplexing B2: Layer 1 Receive Data
TDMB2 receives serial data from L1RXD.
