Low Voltage Detect Enable
0: Disable Low Voltage Detect
1: Enable Low Voltage Detect
Setting this bit to 1 will generate a LVD event when the V
the voltage set by LVDS bits. Therefore when the LVD function is enabled before
the system is into the Deep-Sleep2 (DMOS is turn on and LDO is power down) or
Power-Down mode (DMOS and LDO is power down), the LVDEWEN bit has to
be enabled to avoid the LDO does not activate in the meantime when the CPU is
woken up by the low voltage detection activity.
