8.29 READ EXTENDED READ PARAMETERS OPERATION (RDERP, 81h)

Prior to, or after setting Extended Read Register, the data of the Extended Read Register can be confirmed by the

RDERP command. The instruction is only applicable for the volatile Extended Read Register, not for the non-

volatile Extended Read Register.

During the execution of a Program, Erase or Write Non-Volatile Register operation, the RDERP instruction will be

executed, which can be used to check the progress or completion of an operation by reading the WIP bit.
