STATUS – Status Register
• Bits 3:2 – WINTMODE[1:0]: Window Interrupt Mode Settings
These bits configure the interrupt mode for Analog Comparator Window Mode according to
Table
Table 30-5.
• Bits 1:0 – WINTLVL[1:0]: Window Interrupt Enable
These bits enable the Analog Comparator Window Mode Interrupt and select the interrupt level
as described in
enabled interrupt will trigger according to the WINTMODE setting.
• Bits 7:6 – WSTATE[1:0]: Window Mode Current State
These bits show the current state of the signal if the Window Mode is enabled according to
Table
Table 30-6.
• 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
Bit
