BOIAP
Brown-Out Inhibiting IAP
This bit decides whether IAP erasing or programming is inhibited by brown-out status. This
bit is valid only when brown-out detection is enabled.
1 = IAP erasing or programming is inhibited if V
DD
is lower than V
BOD
.
0 = IAP erasing or programming is allowed under any workable V
DD
.
[2]
CBORST
CONFIG Brown-Out Reset Enable
This bit decides whether a brown-out reset is caused by a power drop below V
BOD
.
1 = Brown-out reset Enabled.
0 = Brown-out reset Disabled.
