Read electronic signature
The device contains a manufacturer code and device code. To read these codes three steps
are required:
1. One bus write cycle to issue the Read Electronic Signature command (90h)
2. One bus write cycle to input the address (00h)
3. Four bus read cycles to sequentially output the data (as shown in Table 14: Electronic
signature).
