Write to Lock Register (WRLR)
The Write to Lock Register (WRLR) instruction allows bits to be changed in the Lock
Registers. Before it can be accepted, a Write Enable (WREN) instruction must previously
have been executed.
Apart form the parallelizing of the instruction code, the address and the input data on the
four pins DQ0, DQ1, DQ2 and DQ3, the instruction functionality is exactly the same as the
Write to Lock Register (WRLR) instruction of the Extended SPI protocol, please refer to
Section 9.1.25: Write to Lock Register (WRLR)
