Optional Parameters
Commands
The Non-default Parameters screen, which contains the preceding
parameters and any default parameters that were changed, is displayed as the
default. The more complex All Parameters screen displays the following
additional parameters. To toggle between the two screens, press F4.
� Memory Begin Address
Specifies the beginning RAM address, in hex, against which the first byte of
data is verified during a verify operation. The Memory Begin Address must
be an even address if you have selected a 16-bit device. The default is 0.
� Device Begin Address
Specifies the first hex device address that will be verified.
� Device Block Size
Specifies the size, in hex, of device data used in device operations. When
you select a device, Device Block Size is automatically set to the device
size and normally does not need to be changed. It is also automatically set
to a smaller value if the Device Begin Address is nonzero. This parameter
can be changed if desired. If a zero is entered, the Device Block Size is set
automatically to equal the device size.
� Set Auto-increment
When enabled, directs the programmer (when in a set verify mode) to the
starting memory address of the next data block that is to be verified. For
example, if you have four 1K x 8 devices to verify against a 4K x 8 block of
data, using the auto-increment option directs the programmer to point to
the first address of the next 1K block after each device has been verified.
For single device operations, this feature should be disabled and the Next
Device parameter should be set to 1.
Note: Items with an * (asterisk) are visible on the screen only if the
selected device supports the feature.
* Compare Electronic ID
When enabled, compares the electronic signature of the device against the
electronic signature of the selected algorithm.
* Odd/Even Byte Swap (Y,N)
When enabled, allows the Most Significant Bytes (MSB) and the Least
Significant Bytes (LSB) of 16-bit words to be swapped when data is verified
between a 16-bit device and memory. When disabled, data is verified with
the MSB at an odd address. When enabled, the MSB is at an even address.
� Verify Passes (0,1,2)
Selects the number of times to test the device.
0—do not to test the device.
1—test the device once at the device manufacturer's nominal Vcc.
2—verify the device at the device manufacturer's recommended high and
low Vcc levels. This is the default.
