 *              A seven character ASCII representation of the product
 *              identifier compressed into a 32-bit identifier. The seven
 *              character ID consists of a three character manufacturer code,
 *              a three character hexadecimal product identifier, and a one
 *              character hexadecimal revision number. The manufacturer code
 *              is a 3 uppercase character code that is compressed into 3 5-bit
 *              values as follows:
 *                  1) Find hex ASCII value for each letter
 *                  2) Subtract 40h from each ASCII value
 *                  3) Retain 5 least significant bits for each letter by
 *                     discarding upper 3 bits because they are always 0.
 *                  4) Compressed code = concatenate 0 and the 3 5-bit values
 *
 *              The format of the compressed product identifier is as follows:
 *              Byte 0: Bit 7       - Reserved (0)
 *                      Bits 6-2:   - 1st character of compressed mfg code
 *                      Bits 1-0    - Upper 2 bits of 2nd character of mfg code
 *              Byte 1: Bits 7-5    - Lower 3 bits of 2nd character of mfg code
 *                      Bits 4-0    - 3rd character of mfg code
 *              Byte 2: Bits 7-4    - 1st hex digit of product number
 *                      Bits 3-0    - 2nd hex digit of product number
 *              Byte 3: Bits 7-4    - 3st hex digit of product number
