ISSP - Conversion of ISSP vectors to hex

Question: The ISSP vectors shown in AN2026 is a long sequence of 1's and 0's.  I would like to create arrays of hex numbers from this sequence.  How do I do this?

 

Answer:

The following procedure may be used to convert a vector to hex value. First split each vector into 22bit sequences. Then pad each sequence with 2 zeros in the beginning. This will make the length of the sequence to be 3 bytes. Then split this into 3 hex values. For example, following is the first 22 bits of the Initialize-1 vector.

 
  1100101000000000000000
  Add 2 zeros in the beginning
  001100101000000000000000
  Now split this into 3 bytes
  00110010, 10000000, 00000000
  32H, 80H, 00H

  For the programming vectors, please refer to the application notes AN2026A or AN2026B.
