Clear Status Register Command
Page Program Command
This command clears the bits (SR3–SR5) which are set when the status register operation ends in
error. When the “50

This command writes the specified page (256 bytes) in the flash memory sequentially one byte at a
time. Execute the page program command as explained here following.
When reception setup for the next 256 bytes ends, the RTS

information, see the section on the status register.
Each block can be write-protected with the lock bit. For more information, see the section on the data
protection function. Additional writing is not allowed with already programmed pages.
