The FSTAT register reports the operational status of the Flash module.
1. Reset value can deviate from the value shown if a double bit fault is detected during the reset sequence (see
CCIF, ACCERR, and FPVIOL bits are readable and writable, MGBUSY and MGSTAT bits are readable
but not writable, while remaining bits read 0 and are not writable.
