Description
Flash Programming Enable
Monitors the level, which is input to the FWE pin that
performs hardware protection of the flash memory
programming or erasing. The initial value is 0 or 1
according to the FWE pin state.
0: When the FWE pin goes low (in hardware protection
1: When the FWE pin goes high
MAT Bit
Indicates whether the user MAT or user boot MAT is
selected.
0: User MAT is selected
1: User boot MAT is selected
Reserved
This bit is always read as 0. The write value should always
