Fig. 68 Timing for clear status register
This command writes the specified page (256 bytes) in the flash
memory sequentially one byte at a time. Execute the page pro-
gram command as explained here following.

Rev.1.01
This command clears the bits (SR4, SR5) which are set when the
status register operation ends in error. When the “50
code is sent with the 1st byte, the aforementioned bits are
cleared. When the clear status register operation ends, the S
(BUSY) signal changes from “H” to “L” level.
