ADCSRB – ADC Control and Status Register B
DIDR0 – Digital Input Disable Register 0
• Bit 7– BIN: Bipolar Input Mode
The gain stage is working in the unipolar mode as default, but the bipolar mode can be
selected by writing the BIN bit in the ADCSRB register. In the unipolar mode only one-sided
conversions are supported and the voltage on the positive input must always be larger than
the voltage on the negative input. Otherwise the result is saturated to the voltage reference. In
the bipolar mode two-sided conversions are supported and the result is represented in the
two’s complement form. In the unipolar mode the resolution is 10 bits and the bipolar mode the
resolution is 9 bits + 1 sign bit.
• Bit 3 – Res: Reserved Bit
This bit is reserved for future use. For compatibility with future devices it must be written to
zero when ADCSRB register is written.
• Bits 2:0 – ADTS2:0: ADC Auto Trigger Source
If ADATE in ADCSRA register is written to one, the value of these bits selects which source
will trigger an ADC conversion. If ADATE is cleared, the ADTS2:0 settings will have no effect.
A conversion will be triggered by the rising edge of the selected Interrupt Flag. Note that
switching from a trigger source that is cleared to a trigger source that is set, will generate a
positive edge on the trigger signal. If ADEN in ADCSRA register is set, this will start a conver-
sion. Switching to Free Running mode (ADTS[2:0]=0) will not cause a trigger event, even if the
ADC Interrupt Flag is set.
