AT90PWM1
Analog Comparator 2 Control Register – AC2CON
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 56. Interrupt sensitivity selection
• 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 57. Analog Comparator 0 negative input selection
