Section 17 Band-Gap Circuit, Power-On Reset, and Low-Voltage Detection Circuits
17.2
The low-voltage detection circuit has the following registers.
17.2.1
LVDCR enables or disables the low-voltage detection circuit and BGR circuit, selects the
compared voltage of the LVDI circuit, sets the detection levels for the LVDR circuit, enables or
disables the LVDR circuit, and enables or disables generation of an interrupt when the power-
supply voltage rises above or falls below the respective levels.
Table 17.1 shows the relationship between the LVDCR settings and functions to be selected.
LVDCR should be set according to table 17.1.
