MC95FG308 / MC95FG208
ABOV Semiconductor Co., Ltd.
13.7 Brown Out Detector Processor
The MC95FG308 has an On-chip Brown-out detection circuit for monitoring the VDD level during operation by
comparing it to a fixed trigger level. The trigger level for the BOD can be selected by BODLS[1:0] bit to be 1.6V, 2.5V,
3.6V or 4.2V. In the STOP mode, this will contribute significantly to the total current consumption. So to minimize the
current consumption, the BODEN bit is set to off by software.
