Overview

The DHDLC IP core is used for controlling HDLC/SDLC transmission frame, no matter if it's 8-, 16- or 32-bit microcontroller. It allows to save MCU time wasted for handling HDLC/SDLC features like bit stuffing, address recognition or CRC computation. The DHDLC has implemented FIFO buffer, for both, receiver and transmitter.

Features

  • Two separate receiver and transmitter interfaces; Two separate, configurable FIFO buffers for receiver and transmitter
  • Bit stuffing and unstuffing; Address recognition for receiver and address insertion for transmitter; ##Two or one byte address field
  • CRC-16 and CRC-32 computation and checking; Collision detection; Byte alignment error detection
  • Programmable number of bits for idle detection; NRZI coding support; Shared flags, shared zeroes support
  • Pad fill with flags option; Transmitter clock generation; 8-bit, 16-bit, 32-bit CPU interface
