27.5.13 Reset During Operation

Program or erase operations must not be interrupted. The content of a block or a page is unpredictable in case of reset during either an erase or a write operation. To reduce the risk of having a BOD reset due to a power loss one can monitor the external voltage before issuing any program or erase operation. The user can also prefer the WQW command instead of the WP command as a short command is more likely to complete successfully than a long one with a given external decoupling capacitor. In case of reset during a write or erase operation the impacted block must be erased before being read or programmed as its content is unknown.
