PSD3XX – Application Note 032
Emulator
PSD3XX
Configuration
The sole function of the Emulator PSD3XX is to access the external program memory
whenever the Microcontroller attempts to access the EPROM memory. The addresses of
the memory blocks corresponding to ES0 – ES7 of the System PSD3XX internal EPROM
Memory Map are programmed into the Emulator PSD3XX, not as ES0 – ES7, but as the
eight PAD product terms for PB0 and PB1. These two outputs are configured as Open
Drain outputs and wire-or’d together into a common Chip Select to the external EPROM
socket. This feature ensures that the Emulator memory is not addressed when the internal
SRAM and I/O of the system PSD3XX are accessed. Also, this allows the Emulator SRAM
to truly emulate the EPROM of the system PSD3XX by eliminating the need for the program
code in the SRAM to be contiguous, by dividing it into eight blocks. Port A is configured to
latch the low order address byte for Microcontrollers with Multiplexed Address/Data Buses.
PC0 – PC2 can be configured for specific Memory and I/O signals which may be required
by the selected Microcontroller. Appendix B contains the generalized Emulator PSD3XX
Configuration Printout (PSDsoft Fitter Output Report).
