ATtiny26(L)
• Bit 4 – ACI: Analog Comparator Interrupt Flag
This bit is set (one) when a comparator output event triggers the interrupt mode defined by ACI1
and ACI0. The Analog Comparator Interrupt routine is executed if the ACIE bit is set (one) and
the I-bit in SREG is set (one). ACI is cleared by hardware when executing the corresponding
interrupt handling vector. Alternatively, ACI is cleared by writing a logic one to the flag.
• Bit 3 – ACIE: Analog Comparator Interrupt Enable
When the ACIE bit is set (one) and the I-bit in the Status Register is set (one), the Analog Com-
parator interrupt is activated. When cleared (zero), the interrupt is disabled.
• Bit 2 – ACME: Analog Comparator Multiplexer Enable
When the ACME bit is set (one) and the ADC is switched off (ADEN in ADCSR is zero),
MUX3...0 in ADMUX select the input pin to replace the negative input to the Analog Comparator,
as shown in Table 42 on page 93. If ACME is cleared (zero) or ADEN is set (one), PA7(AIN1) is
applied to the negative input to the Analog Comparator.
• Bits 1, 0 – ACIS1, ACIS0: Analog Comparator Interrupt Mode Select
These bits determine which comparator events that trigger the Analog Comparator interrupt. The
different settings are shown in Table 41.

clearing its Interrupt Enable bit in the ACSR Register. Otherwise an interrupt can occur when
the bits are changed.
