| * 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 signficant 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 |
