19.2
The low-voltage detection circuit has the following registers.
19.2.1
LVDCR is used to enable or disable the low-voltage detection circuit, set the detection levels for
the LVDR function, enable or disable the LVDR function, and enable or disable generation of an
interrupt when the power-supply voltage rises above or falls below the respective levels.
Table 19.1 shows the relationship between the LVDCR settings and select functions. LVDCR
should be set according to table 19.1.

0: The low-voltage detection circuit is not used (In
1: The low-voltage detection circuit is used
Reserved
These bits are always read as 1 and cannot be modified.
LVDR Detection Level Select
0: Reset detection voltage is 2.3 V (typ.)
1: Reset detection voltage is 3.6 V (typ.)
When the falling or rising voltage detection interrupt is
used, reset detection voltage of 2.3 V (typ.) should be
used. When only a reset detection interrupt is used, reset
detection voltage of 3.6 V (typ.) should be used.
LVDR Enable
0: Disables the LVDR function
1: Enables the LVDR function
