TOP432s installed on the programmer. In this mode, all devices inserted into all of

the TOPs will receive the same programming information.

The TOP432 is unique because it has both gang and set programming capabilities. By

default the TOP432 is in the gang programming mode, where each device is

programmed with the same data. If you want to change to set programming, click on

the TOP432 icon. When the TOP432 icon appears, select SET-Mode programming.

In set mode, you have the option of 8, 16 or 32 bit programming mode:

8 Bit Mode

Select the 8 Bit mode when a large data file needs to be programmed over multiple

memory devices. In the example below the 64K file data is programmed into four

16K memory devices. The first 16K (0000-3FFF) is programmed into socket 1, the

second 16K (4000-7FFF) into socket 2, the third 16K (8000-BFFF) into socket 3, and

the fourth 16K (C000-FFFF) into socket 4.

The TOP432 creates the division of data automatically. The file is downloaded, the 8

Bit mode is selected and the programming operation is started.

16 Bit Mode

Select the 16 Bit mode when a 16 Bit data file needs to programmed into two 8 Bit

devices. In the example below the file data is a 16 Bit format. As the file data is read

during the programming operation, the TOP432 software places the low order bytes in

sockets 1 and 3. The high order bytes are placed in sockets 2 and 4.

Note: Often low order bytes are referred to as EVEN bytes and high

order bytes as ODD bytes.

The TOP432 creates the division of data automatically. The file is downloaded, the 16

Bit mode is selected and the programming operation is started.

32 Bit Mode

Select the 32 Bit mode when a 32 Bit data file needs to programmed into four 8 Bit

devices. In the example below the file data is a 32 Bit format. As the file data is read

during the programming operation, the TOP432 software places low order data bytes

(D0-D7) in socket 1. Data bytes (D8-D15) are placed in socket 2, data bytes (D16-

D23) are placed in socket 3, and the high order bytes (D24-D310) are placed in

socket 4.

The TOP432 creates the division of data automatically. The file is downloaded, the 32

Bit mode is selected and the programming operation is started.
