184.108.40.206. Read Non-Volatile Configuration Register Operation (B5h)
To execute a read non-volatile configuration register, drive the nCS low. For extended SPI protocol, the operation code is input on DATA0, and output on DATA1. You can terminate the operation by driving the nCS low at any time during data output. The nonvolatile configuration register can be read continuously. After all 16 bits of the register have been read, a 0 is output.
