`Two independent full-duplex HDLC channels (SAB 82526: one channel)
- On chip clock generation or external clock source
- On chip DPLL for clock recovery for each channel
- Two independent baudrate generators (SAB 82526: one baudrate generator)
- Independent time-slot assignment for each channel with programmable time-slot length (1-256 bit)
`Different modes of data encoding
`Modem control lines (RTS, CTS, CD)
`Support of bus configuration by collision resolution
`Programmable bit inversion
`Transparent receive/transmit of data bytes without HDLC framing
`Continuous transmission of 1 to 32 bytes possible
`Data rate up to 4 Mbit/s
Protocol Support
`Various types of protocol support depending on operating mode
- Auto-mode
- Non-auto mode
- Transparent mode
`Handling of bit oriented functions in all modes
`Support of LAPB/LAPD/SDLC/HDLC protocol in auto-mode (I- and S-frame handling)
`Modulo 8 or modulo 128 operation
`Programmable time-out and retry conditions
`Programmable maximum packet size checking
P Interface
`64 byte FIFO's per channel and direction
`Storage capacity of up to 17 short frames in receive direction
`Efficient transfer of data blocks from/to system memory by DMA or interrupt request
