SAB 82538
SAF 82538
This solution supports applications with a high speed data rate in one serial channel with
minimum hardware expense making use of the on-chip peripheral functions of the 80188
(chip select logic, interrupt controller, DMA controller).
1.4.2.2 ESCC8 with 80386
In high-performance 32-bit systems based on an 80386 microprocessor a separate
control logic (e.g. sequencer PALs) is normally provided to generate all necessary
control signals for interfacing to I/O devices. Address and data lines are buffered via
latches or transceivers. An interface to ESCC8 is for this case sketched in figure 5.
