3.2
3.2.1
The SCC is a multi-protocol communication controller. The core logic provides different
protocol modes which are listed below:
• HDLC Modes
• Point-to-Point Protocol (PPP) Modes
• Extended Transparent Mode
A detailed description of these protocol modes is given in
Page
3.2.2
Each SCC provides its own transmit and receive FIFOs to handle internal arbitration and
microcontroller latencies.
3.2.2.1
The SCC transmit FIFO is divided into two parts of 32 bytes each (’transmit pools’). The
interface between the two parts provides synchronization between the microprocessor
accesses and the protocol logic working with the serial transmit clock.
