Atmel ATA6612/ATA6613
Analog Comparator Multiplexed Input
Digital Input Disable Register 1 – DIDR1
Table 6-95.
When changing the ACIS1/ACIS0 bits, the Analog Comparator Interrupt must be disabled by
clearing its Interrupt Enable bit in the ACSR Register. Otherwise an interrupt can occur when
the bits are changed.
It is possible to select any of the ADC7..0 pins to replace the negative input to the Analog
Comparator. The ADC multiplexer is used to select this input, and consequently, the ADC
must be switched off to utilize this feature. If the Analog Comparator Multiplexer Enable bit
(ACME in ADCSRB) is set and the ADC is switched off (ADEN in ADCSRA is zero), MUX2..0
in ADMUX select the input pin to replace the negative input to the Analog Comparator, as
shown in
to the Analog Comparator.
Table 6-96.

• Bit 1, 0 – AIN1D, AIN0D: AIN1, AIN0 Digital Input Disable
Initial Value
Read/Write
ACME
ACIS1
These bits are unused bits in the Atmel
zero.
When this bit is written logic one, the digital input buffer on the AIN1/0 pin is disabled. The
corresponding PIN Register bit will always read as zero when this bit is set. When an ana-
log signal is applied to the AIN1/0 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.
