Description
LVD Enable
0: Low-voltage detection circuit is not used (standby
mode)
1: Low-voltage detection circuit is used
BGR Enable
0: BGR circuit is not used (standby mode)
1: BGR circuit is used
LVDR External Compared Voltage Input Inhibit
0: Use external voltage as LVDI compared voltage
1: Use internal voltage as LVDI compared voltage
Reserved
This bit is 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, the 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 an LVDR
1: Enables an LVDR
Voltage-Fall-Interrupt Enable
0: Interrupt on the power-supply voltage falling disabled
1: Interrupt on the power-supply voltage falling enabled
Voltage-Rise-Interrupt Enable
0: Interrupt on the power-supply voltage rising disabled
1: Interrupt on the power-supply voltage rising enabled
