The ESCC2 (SAB 82532/SAF 82532) comprises two completely independent
full-duplex serial interfaces (channel A and channel B) 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 versions SAB/SAF 82532 N-10
and SAB/SAF 82532 H-10). Encoding/decoding of serial data can be done by using
NRZ, NRZI, FM0, FM1 and Manchester encoding schemes. An 8-bit universal
bi-directional 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
ESCC2 by means of a 4-channel DMA interface with one DMA request line for each
transmitter and receiver of both channels. The interrupt structure of ESCC2 supports
interrupt driven systems using interrupt polling, daisy chaining or interrupt vector control.
