DATA
This page (see
Figure 7
) allows the user to program the 1 K-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 K-Bit EPROM
The EPROM memory map is organized in four 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 EVSW 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
EVSW. 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. Click on the
Write
Memory
button so that the values are programmed into the EPROM.
