13.7 Brown Out Detector Processor
The MC96F6432 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.
