UniSite-xpi User Manual 4-13
* Compare Electronic ID (Y,N)—Compares the electronic ID of the
socketed device against the electronic ID 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 loaded from a 16-bit device. When
disabled, the data from a 16-bit device is loaded into User RAM with
the MSB stored at an odd memory address. When enabled, the MSB
is stored at an even memory address.
