Mode settings table 2 / 2
D0 : Shutdown
“0” - Operation mode.
“1” - The BU9817FV stops A / D operation and goes into low power shutdown mode.
D0 bit of each channel is common bit.
D1 : Comparator / Interrupt mode
“0” - Comparator mode.
“1” - Interrupt mode.
D2 : Open Drain Polarity
“0” - active low.
“1” - active high.
D3 : Reset
“0” - Operation mode.
“1” - Reset any bits except D3 bit of the configuration register, any registers, the A / D converter, and the
voltage hysteresis comparator.
D3 bit of each channel is common bit.
D4 : Interval Speed
Set the conversion cycle time of the 8bit A / D and the voltage hysteresis comparator when D5 bit (Interval
Mode) is “1”.
“0” - conversion cycle time is 4s.
“1” - conversion cycle time is 1s.
D4 bit of each channel is common bit.
D5 : Interval Mode
“0” - normal mode.
“1” - Interval mode.
D5 bit of each channel is common bit.
