PSD3XX – Application Note 032
The Emulator functions by replacing the system’s EPROM with SRAM. To accomplish this,
when the system PSD3XX is configured by the PSDsoft software, ES0 – ES7 are
disabled (i.e., not defined in the PSDabel source file) to prevent their eight respective
internal EPROM blocks from attempting to access the external Data Bus. Reference
Figure 5 – PSD3XX PAD Description. Appendix A contains the generalized System
PSD3XX Configuration Printout (PSDsoft Fitter Output Report) corresponding to the
Interface Diagram in Figure 2 and the Memory Map in Figure 6 configured as an example.
The Address Map is configured such that all routines are accessible from either Page 1 or
Page 2 of main memory.
Note:
The Address Map Equations in Appendix A shows ES0 – ES7 active to illustrate the
block addresses which will be controlled by PB0 – PB1 in the Emulator PSD3XX.
ES0 – ES7 are left blank in the actual chip configuration.

Figure 5. PSD3XX PAD Description
NOTES:
1. CSI is a power-down signal. When high, the PAD is in stand-by mode and all its outputs become
non-active.
2. RESET deselects all PAD output sigals
3. A18, A17, and A16 are internally multiplexed with CS10, CS9, and CS8, respectively. Either A18 or
CS10, A17 or CS9, and A16 or CS8 can be routed to the external pins of Port C. Port C can be
configured as either input or output.
