13.7 Brown Out Detector Processor
The MC97F60128 has an On-chip brown-out detection circuit (BOD) 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 LVRVS[3:0] bit to be 1.60V, 2.00V,
2.10V, 2.20V,2.32V, 2.44V, 2.59V, 2.75V, 2.93V, 3.14V, 3.38V, 3.67V, 4.00V, 4.40V. In the STOP mode, this will
contribute significantly to the total current consumption. So to minimize the current consumption, the LVREN bit is set
to off by software.
