BODVL
Brown-out Detector Threshold Voltage Selection (Write Protected)
The default value is set by flash controller user configuration register CBOV (CONFIG0
[23:21]).
000 = Brown-Out Detector threshold voltage is 1.6V.
001 = Brown-Out Detector threshold voltage is 1.8V.
010 = Brown-Out Detector threshold voltage is 2.0V.
011 = Brown-Out Detector threshold voltage is 2.2V.
100 = Brown-Out Detector threshold voltage is 2.4V.
101 = Brown-Out Detector threshold voltage is 2.6V.
110 = Brown-Out Detector threshold voltage is 2.8V.
111 = Brown-Out Detector threshold voltage is 3.0V.
Note:
These bits are write protected. Refer to the SYS_REGLCTL register.
