SMC2: Serial Management Receive Data
Supported by SMC2. 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 Nibble Receive
Data Bit 0
In the TDMA1 interface supported by SI1. L1RXD3 is the most
significant bit. L1RXD0 is the least significant bit in nibble
mode. TDMA1 receives nibble data from L1RXD[0–3].
Time-Division Multiplexing A1: Layer 1 Serial Receive
Data
In the TDMA1 interface supported by SI1. TDMA1 receives
serial data from L1RXD.
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/Grant
In the TDMA1 interface supported by SI1, this is the
synchronizing signal for the transmit channel. If Grant Mode is
enabled this bit is sampled as the Grant bit for IDL mode
access for the D channel. See the Serial Interface with
Time-Slot Assigner chapter in the MSC8101 Technical
Reference manual.
Time-Division Multiplexing A1: Layer 1 Receive
Synchronization.
In the TDMA1 interface supported by SI1, this is the
synchronizing signal for the receive channel.
