LVD_TRIM
Description
Reserved
These bits are reserved and must be programmed to 111.
Low Voltage Detect Trim m
This trimming affects the low voltage detection threshold. Each LSB represents a 50 mV
change in the threshold level. Alternatively, the low voltage threshold may be computed from
the options bit value by the following equation:
LVD_LVL = 3.6 V – LVD_TRIM  0.05 V
These values are tabulated in Table 94.
