These bits are always read as 0. The write value should
always be 0.
Status Error
Indicates the result of status read. This bit is set to 1 if
the specific bit in bits STAT7 to STAT0 in FLBSYCNT is
set to 1 in status read.
Since this bit is a flag bit, 1 cannot be written to this bit.
Only 0 can be written to clear the flag.
0: Indicates that no status error occurs (the specific bit
