Figure 17.6 Operational Timing Of Lvdi Circuit (When Compared Voltage Is Input Through Extu And Extd Pins)) - Renesas H8/36912 Series User Manual

If the power supply voltage falls below the Vreset1 (Typ. = 2.3 V) voltage, this LSI enters low-
voltage detection reset operation. When the voltages input on the ExtU and ExtD pins are used as
the compared voltage, ensure to use the LVDR (reset detection voltage: Typ. = 2.3 V) circuit.
