WINCTRL – Analog Comparator Window Function Control Register
STATUS – Analog Comparator Common Status Register
• Bits 5:0 - SCALEFAC[5:0]: Analog Comparator Input Voltage Scaling Factor
These bits define the scaling factor for the Vcc voltage
V
• Bits 7:5 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 4 - WEN: Analog Comparator Window Enable
Setting this bit enables Window Mode for the two Analog Comparators on the same port.
• Bits 3:2 - WINTMODE[1:0]: Analog Comparator Window Interrupt Mode Settings
These bits configure the interrupt mode for Analog Comparator Window Mode according to
Table
Table 21-5.
• Bits 1:0 - WINTLVL[1:0]: Analog Comparator 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]: Analog Comparator Window Mode Current State
These bits show the current state of the signal if the Window Mode is enabled according to
