SMC1: Receive Data
Supported by SMC1. 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).
Serial Interface 2: Layer 1 Strobe 4
In the time-slot assigner supported by SI2. The MSC8101 time-slot
assigner supports up to four strobe outputs that can be asserted on
a bit or byte basis. The strobe outputs are useful for interfacing to
other devices that do not support the multiplexed interface or for
enabling/disabling three-state I/O buffers in a multiple-transmitter
architecture. These strobes can also generate output wave forms
for such applications as stepper-motor control.
FCC2: Carrier Detect
In the standard modem interface signals supported by FCC2 (RTS,
CTS and CD). CD is asynchronous with the data.
