Architecture
MSC8101 Overview 1-11
The MCC also supports super channels of rates higher than 64 Kbps and
subchanneling of the 64 Kbps channels.
■ Four full-duplex serial communication controllers (SCCs) supporting
IEEE802.3/Ethernet, synchronous data link control, high-level data link control
protocol (HDLC), local talk, UART, Synchronous UART, BISYNC, and
transparent mode. Two SCCs have dedicated pins; the other two can operate only
in TDM mode.
■ Two full-duplex SMCs supporting general circuit interface (GCI), UART, and
transparent operation.
■ SPI and I

C bus controllers.
■ Two serial interfaces (SIs) with time-slot assigners (TSAs) that support
multiplexing of data from any of the three FCCs, two MCCs, four SCCs, and two
SMCs.
■ A time-slot assigner (TSA) that supports multiplexing of data from any of the four
SCCs, three FCCS, and two SMCs.
The CPM includes many other functions; the preceding list is an overview of major
features.
