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.
