Commands
� Memory Begin Address
Specifies the first hex address in RAM to load data from a device. Also
specifies the first address where a device is programmed/verified. If the
user memory is RAM, it is a beginning RAM address. If the user memory is
disk, it is a beginning disk file address. The Memory Begin Address must be
an even address if you selected a 16-bit device. The default address is 0.
� Device Begin Address
Specifies the first address used in device operations. This option is used for
memory devices only.
� Device Block Size
Defines the size, in hex, of device data used in device operations. When
you select a device, Device Block Size is 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 to the device size.
� Illegal Bit Check (Y,N)
Enables or disables the illegal-bit test. This test compares data in a device
against data in the programmer's RAM to determine if the device has
already-programmed locations of incorrect polarity.
For example, the programmer returns an illegal-bit error in the following
situation: data in RAM indicates a specific bit should be in an
unprogrammed state while the corresponding bit in the device is in a
programmed state. This parameter is enabled by default.
� Blank Check (Y,N)
Enables or disables the blank check test. A Blank Check test checks a
device for programmed bits. This parameter defaults to Y, which enables
the test.
� Compare Elec ID (Y,N)
Compares the electronic ID of the device against the electronic ID of the
selected algorithm.
� Enable Yield Tally (Y,N)
When enabled, directs the programmer to keep a running tally of the
programming yields for the last sixteen types of devices programmed.
These totals show how many devices passed and failed, and what specific
errors, if any, have occurred. This parameter defaults to N, which disables
the test. A more complete description of this feature can be found in the
“Yield Tally” section of this chapter.
� Program Security Fuse (Y,N)
Enables or disables the programming of the security fuse. To program the
security fuse, set this parameter to Y and set the Security Fuse Data
parameter to 1. This parameter defaults to N, which disables programming
of the security fuse.
� Erase EE Device (Y,N)
Bulk erases the electronically erasable devices before the programmer
attempts to program them.
� Odd/Even Byte Swap (Y,N)
When enabled, swaps data at memory address locations during a load,
program, or verify operation. The contents of user RAM are not altered.
