HARDWARE OVERVIEW

If this text does not display on the LED, indicating a problem with the jumper assembly, the board boots as if no Flash loader assembly is installed; that is, the Flash target program immediately starts the loaded user application program (for example, the iRISM monitor software).

You can find complete instructions for using the Flash utility program in the CQI Flash Loader User Manual included in your kit.

3.3.2SRAM (Static Memory)

SRAM occupies the lower 128 Kbytes of memory starting at location 00000H. This memory is used by the processor for interrupt vectors and stack allocation, by the RISM for program variables, and by the user for downloaded code. The board includes two 1-Mbit, 32-pin SRAMs with 17 ns access time at 3.3 volts. SRAMs are socketed to allow installation of 5 V SRAMs (17 ns access time).

To allow insertion of both the 80x186 processor and the 80x188 processor, the memory is configured such that only 128 Kbytes of the SRAM is accessible, even though 256 Kbytes of SRAM are installed on the board.

3.4PROGRAMMABLE LOGIC

All glue logic required by the evaluation board is implemented on a GAL 22LV10C-15. The PLD file located on the floppy diskette in your kit includes logic equations for this device. The logic implemented includes the following:

•Inverting the Port Pin signal controlling VPP (so VPP is disabled at reset)

•Controlling the 8-bit/16-bit configuration for the Flash device

•Decoding the Enable signal for the LCD display
