NOTE: The Fill memory menu item accepts values in relation to the

device to be processed. It is often necessary to know the

block size of the specific device being used. Many devices

do not support partial programming operations. Therefore,

partially filling RAM with a data pattern is not supported

with those devices. Because of this, an error will occur if

you attempt to fill RAM with less data than the device

supports. Also, filling RAM beyond the block size of the

device will produce a similar error.

x Swap bytes—Allows you to transpose high and low order bytes within the data

file

x Search for byte—Allows you to search the memory array for a specific data

string.

Selecting Search for Byte produces this window:

“Search for byte” allows you to locate a hex string within memory array

x Repeat search—Performs the Search for byte operation again with the

previously entered search data

You may also select Memory>Fill to fill memory with a hexadecimal data pattern.

Once selected, the following screen will appear:

Memory>Swap Bytes

In cases where the data bytes must be reversed in the data file to accommodate a

specific device, select Memory> Swap Bytes (or select Memory>Edit and right

click to select Swap Bytes). This function allows you to transpose odd and even order

bytes within the data file.

Memory>Address Range

For devices that support partial operations, or if the data file is required to begin at a

specific location, the Address Range… menu item may be used to establish the

programming area of the device. Selecting the Memory>Address Range… produces

the following dialogue:

Setting the device address range

In this dialogue, you can specify the starting and ending addresses. In the example

shown, the start address is set to 100:

Start address set to 100

The file load operation will cause data to be loaded starting at address location hex

100. If a programming operation is performed, data will be programmed from location

100 to 1FFFF
