OSC1=ON (clock is not supplied to the divider and peripheral circuit), OSC3=OFF, CPU clock=OSC1, SVD=OFF,
reset circuit is not selected
OSC1=ON, OSC3=OFF, CPU clock=OSC1, SVD=OFF, reset circuit is not selected
OSC1=ON, OSC3=OFF, CPU clock=OSC1, SVD=OFF, reset circuit is selected
OSC1=ON, OSC3=ON, CPU clock=OSC3, SVD=OFF, reset circuit is not selected
Reset status due to supply voltage detection by the reset circuit, OSC1=ON, OSC3=ON, CPU clock=OSC3, SVD=OFF,
reset circuit is selected, LCD OFF, higher VDD increases current consumption.
When LPWR = "1", current consumption is increased for a cycle of 2 kHz, then it is decreased and stabilized. Also current
consumption of the LCD circuit varies according to the OSC1 clock frequency.
Current consumption of the reset circuit varies slightly depending on the option selected. The table lists the values when
1.4 V option is selected (1.4 V option has the largest current consumption under the same VDD conditions).
