detection voltage, whether to enable or disable voltage detect operation and the action to be taken when the supply
voltage (VDD) falls to or below the detection voltage (VDxLVL) can be programmed by software.
Function
The voltage detecting circuit allows two detection voltage levels (VDxLVL, x = 1, 2) to be specified. For each

interrupt request signals. When VDCR2<VDxMOD> is set to "1", the operation mode is set to generate voltage
detection reset signals.
Enabling/Disabling Voltage Detection Operation
Selecting the Voltage Detect Operating Mode
Setting the VDCR2<VDxEN> bit to 1 enables voltage detect operation and clearing this bit to 0 disables it.
When VDCR2<VDxMOD> is set to "0", the voltage detection operation mode is set to generate INTVLTD
Note:Setting VDCR2<VDxEN> to 1 while the supply voltage is below the detection voltage (VDD<VDxLVL)

request signals may be generated frequently when the supply voltage (VDD) is close to the detection
voltage (VDxLVL). INTVLTD interrupt request signals may be generated not only when the supply voltage
falls to the detection voltage but also when it rises to the detection voltage.

detection reset signal is generated continuously as long as the supply voltage (VDD) is lower than the
detection voltage (VDxLVL).
