DATA

This page (see Figure 7) allows the user to program the 1.5K-bit EPROM with desired values and to

program the STATUS bytes. It requires that the hardware is set up as described in the EPROM

programming of this user's guide.

8.3.1

1.5K-Bit EPROM

The EPROM memory map is organized in six pages of 32 bytes each. All registers can be read by clicking

on the Read Memory button. As the registers of a specific page are being read, the page number is

highlighted in red.

The two methods of programming the EPROM using the evaluation program follow.

1. Click on a specific grid that corresponds to the register that needs to be written. Write the hexadecimal

value of the data that needs to be written, and then press ENTER.

2. The other method of programming the EPROM is by importing a data file that contains all the values to

be programmed. The data file has the file extension .epr. An example of a data file is included with the

evaluation program. To create additional data files, modify the example file so that the values on the

right side of the file represent the desired values. Save the file with a different name ensuring that the

extension .epr is used. To import a file into the grid, go to File

→ Open Data File, and select the

appropriate file. Once the file is opened, the grid is filled in with the values contained in the data file.
