Using the EMSIM Registers
The 6833x processor contains a System Integration Module (SIM) which has
the external bus interface, 12 chip selects, and other circuitry to reduce
external logic in a typical microprocessor system. The SIM can be
programmed or configured in a variety of ways to suit the need of various
systems.
The HP 64782 emulator contains circuitry that accommodates the flexibility
of the SIM and maintains consistent emulation features.
