Read-Electronic-Signature (RES)
The RES instruction can be used to read the 8-bit Electronic
Signature of the device on the SO pin. The RES instruction can
provide access to the Electronic Signature of the device (except
while an Erase, Program or WRSR cycle is in progress), Any
RES instruction executed while an Erase, Program or WRSR
cycle is in progress is no decoded, and has no effect on the cycle
in progress. In OTP mode, user also can execute RES to confirm
the status.
