ADCSRB – ADC Control and Status Register B
DIDR0 – Digital Input Disable Register 0
The ADLAR bit in ADMUX, and the MUXn bits in ADMUX affect the way the result is read from
the registers. If ADLAR is set, the result is left adjusted. If ADLAR is cleared (default), the result
is right adjusted.
• ADC[9:0]: ADC Conversion Result
These bits represent the result from the conversion, as detailed in
page
• Bits 7, 5:3 – Res: Reserved Bits
These bits are reserved bits in the ATtiny13A and will always read as zero.
• Bits 2:0 – ADTS[2:0]: ADC Auto Trigger Source
If ADATE in ADCSRA is written to one, the value of these bits selects which source will trigger
an ADC conversion. If ADATE is cleared, the ADTS[2:0] settings will have no effect. A conver-
sion 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 is set, this will start a conversion. Switching to Free Running
mode (ADTS[2:0]=0) will not cause a trigger event, even if the ADC Interrupt Flag is set
Table 14-5.
• Bits 5:2 – ADC3D:ADC0D: ADC[3:0] Digital Input Disable
When a bit is written logic one, the digital input buffer on the corresponding ADC pin is disabled.
The corresponding PIN register bit will always read as zero when this bit is set. When an analog
signal is applied to the ADC[7:0] pin and the digital input from this pin is not needed, this bit
should be written logic one to reduce power consumption in the digital input buffer.
