Read Electronic Signature

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

are required:

1. first use one Bus Write cycle to issue the Read Electronic Signature command (90h),

followed by an address input of 00h.

2. then perform two Bus Read operations – the first will read the Manufacturer Code and

the second, the Device Code. Further Bus Read operations will be ignored.

Refer to Table 12: Electronic signature, for information on the addresses.
