ACnMUXCTRL – Analog Comparator Control Register
• Bits 5:4 - INTLVL[1:0]: Analog Comparator Interrupt Level
These bits enable the Analog Comparator n Interrupt and select the interrupt level as described
in
rupt will trigger according to the INTMODE setting.
• Bit 3 - HSMODE: Analog Comparator High-Speed Mode Select
Setting this bit selects High-speed mode and clearing this bit to select Low-power mode.
• Bits 2:1 - HYSMODE[1:0]: Analog Comparator Hysteresis Mode Select
These bits select hysteresis according to
to device datasheet.
Table 21-2.
• Bit 0 - ENABLE: Analog Comparator Enable
Settings this bit enables the Analog Comparator n.
• Bits 7:6 - 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.
• Bits 5:3 - MUXPOS[2:0]: Analog Comparator Positive Input MUX Selection
These bits select which input to be connected to the positive input of Analog Comparator n,
according to
Table 21-3.
