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.

Description
LVD Enable
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
Voltage-Fall-Interrupt Enable
0: Interrupt on the power-supply voltage falling below the
1: Interrupt on the power-supply voltage falling below the
standby mode)
