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 27-5.
• 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
page
• 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
