Table 27-6.
• Bit 5 - AC1STATE: Analog Comparator 1 Current State
This bit shows the current state of the input signal to Analog Comparator 1.
• Bit 4 - AC0STATE: Analog Comparator 0 Current State
This bit shows the current state of the input signal to Analog Comparator 0.
• Bit 3 - Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bit 2 - WIF: Analog Comparator Window Interrupt Flag
This is the interrupt flag for the Window Mode. WIF is set according to the WINTMODE setting in
the
page
The WIF is automatically cleared when the analog comparator window interrupt vector is exe-
cuted. The flag can also be cleared by writing a one to its bit location.
• Bit 1 - AC1IF: Analog Comparator 1 Interrupt Flag
This is the interrupt flag for Analog Comparator 1. AC1IF is set according to the INTMODE set-
ting in the corresponding
page
The AC1IF is automatically cleared when the analog comparator 1 interrupt vector is executed.
The flag can also be cleared by writing a one to its bit location.
• Bit 0 - AC0IF: Analog Comparator 0 Interrupt Flag
This is the interrupt flag for Analog Comparator 0. AC0IF is set according to the INTMODE set-
ting in the corresponding
page
The AC0IF is automatically cleared when the analog comparator interrupt vector is executed.
The flag can also be cleared by writing a one to its bit location.
