RISC Microcode from RAM
C.4 ASYNCHRONOUS HDLC FOR PPP
Asynchronous HDLC is a frame-based protocol (see Figure 3), defined by the Internet Engi-
neering Task Force (IETF) "Request For Comments #1549" which uses HDLC framing tech-
niques in conjunction with UART-type characters. This protocol is typically used as the
physical layer for the Point-to-Point (PPP) protocol. While this protocol can be implemented
by the UART controller on the QUICC in conjunction with the CPU32+, it is more efficient
and less compute-intensive for the CPU to allow the Communications Processor Module
(CPM) of the QUICC to perform the framing and transparency functions of the protocol.
C.4.1 Key Features
C-6
• Flexible data buffer structure which allows an entire frame or a section of a frame to be
• Separate interrupts for received frames and transmitted buffers.
• Automatic 16-bit CRC generation and checking (CRC-CCITT).
• Automatic generation of opening and closing flags.
