It is not recommended to update status and configuration registers of our flash device S25FL512S at every power up. It will use the endurance cycles of status and configuration registers and make them wear out fast. Please see more details about our recommended best practice to update status and configuration register using WRR command in the following application note: https://www.cypress.com/documentation/application-notes/an200381-best-practice-wrr-command-spi-devices .
Thanks and Regards,
Well noted. Thanks for the advice.
