SAB 82538
SAF 82538
The ESCC8 (SAB 82538) comprises eight completely independent full-duplex serial
interfaces which support HDLC/SDLC, BISYNC and ASYNC protocols. Layer-1
functions are performed by means of internal oscillator, Baud Rate Generator (BRG),
Digital Phase Locked Loop (DPLL), and Time-Slot Assignment circuits (TSA, only
available for version SAB 82538H-10). Encoding / decoding of serial data can be done
by using NRZ, NRZI, FM0, FM1, and Manchester encoding schemes.
An 28-bit universal port is provided which can be used for additional modem control lines
or for general I/O purposes.
Associated with each serial channel is a set of independent command and status
registers and 64-byte deep FIFOs for transmit and receive direction. Access is done via
the flexible 8/16-bit microprocessor interface. DMA capability has been added to the
ESCC8 by means of a 16-channel DMA interface with one DMA request line for each
transmitter and receiver of both channels. The interrupt structure of ESCC8 supports
interrupt driven systems using interrupt polling, daisy chaining or interrupt vector control.
