Datasheet
• Bandgap on only, used for stabilization and startup
• High power buffer mode
• Low-power buffer mode
• Buffer disabled
A 100 nF capacitor must always be connected between VERF output (VREFO) pin and
VSSA if the VREF is used. This capacitor must be as close to VREFO pin as possible.
2.2.6 CMP
The device contains one high-speed comparator and two 8-input multiplexers for both
the inverting and non-inverting inputs of the comparator. Each CMP input channel
connects to both muxes.
The CMP includes one 6-bit DAC, which provides a selectable voltage reference for
various user application cases. Besides, the CMP also has several module-to-module
interconnects in order to facilitate ADC triggering, TPM triggering, and interfaces.
The CMP has the following features:
• Inputs may range from rail to rail
• Programmable hysteresis control
• Selectable interrupt on rising-edge, falling-edge, or both rising or falling edges of
the comparator output
• Selectable inversion on comparator output
• Capability to produce a wide range of outputs such as sampled, digitally filtered
• External hysteresis can be used at the same time that the output filter is used for
internal functions
• Two software selectable performance levels: shorter propagation delay at the
expense of higher power and Low power with longer propagation delay
• DMA transfer support
• Functional in all modes of operation except in VLLS0 mode
• The window and filter functions are not available in Stop, VLPS, LLS, or VLLSx
modes
• Integrated 6-bit DAC with selectable supply reference source and can be power
down to conserve power
• Two 8-to-1 channel mux
