Voltage Detection Circuit
R_LVD_Create
Synopsis
Configure the voltage detection circuit.
Prototype
bool R_LVD_Create(
uint16_t data1,
uint16_t data2
);
Description
// Monitor 1 Configuration selection
// Monitor 2 Configuration selection
Set the voltage detection configuration.
[data1]
Monitor 1 voltage detection configuration.
If the monitor is not required specify PDL_NO_DATA, otherwise use “|” to separate each
selection.
• Operation.

Select no action, a reset
on low voltage detection
or non-maskable interrupt
when a specified voltage
event is detected.
Configure the digital filter.
[data2]
