MFR_STR

Manufacturer String, UNICODE UTF-16LE per USB 2.0 specification

 

 

When supported, the maximum string length is 31 characters (62 bytes).

 

 

Note: The string consists of individual 16-bit UNICODE UTF-16LE

 

 

characters. The Characters will be stored starting with the LSB at

 

 

the least significant address and the MSB at the next 8-bit location

 

 

(subsequent characters must be stored in sequential contiguous

 

 

address in the same LSB, MSB manner). Some EEPROM

 

 

programmers may transpose the MSB and LSB, thus reversing the

 

 

Byte order. Please pay careful attention to the Byte ordering or

 

 

your selected programming tools.
