26.4 Operation of Voltage Detector
26.4.1 When used as reset mode
ï‚· When starting operation
Start in the following initial setting state.
Specify the operation mode (the reset mode (LVIMDS1, LVIMDS0 = 1, 1)) and the detection voltage (V
LVD) by
using the option byte 000C1H/020C1H.
ï‚· Set bit 7 (LVISEN) of the voltage detection register (LVIM) to 0 (disable rewriting of voltage detection level
register (LVIS))
ï‚· When the option byte LVIMDS1 and LVIMDS0 are set to 1, the initial value of the LVIS register is set to 81H.
Bit 7 (LVIMD) is 1 (reset mode).
Bit 0 (LVILV) is 1 (low-voltage detection level: V
LVD).
Figure 26-4 shows the timing of the internal reset signal generated by the voltage detector.
