Read Electronic Signature

The device contains a Manufacturer Code and Device Code. To read these codes three steps

are required:

one Bus Write cycle to issue the Read Electronic Signature command (90h)

one Bus Write cycle to input the address (00h)

four Bus Read Cycles to sequentially output the data (as shown in Table 14: Electronic

Signature).
