AT90PWM2/3/2B/3B
Analog Comparator 1Control Register – AC1CON
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 20-1.
• Bit 2, 1, 0– AC0M2, AC0M1, AC0M0: Analog Comparator 0 Multiplexer register
These 3 bits determine the input of the negative input of the analog comparator.
The different setting are shown in
Table 20-2.
