COMP (Analog Comparator)

group group_hal_impl_comp

On CAT1 (PSoC 6), the COMP driver can use either of two underlying hardware blocks:

• Opamp (configured as analog comparator)

• LPComp (Low Power Comparator)

Generally, a set of pins can only connect to either an Opamp or an LPComp but not both. In the event that both connections are possible, the LPComp will be preferred.

Power Level Mapping

The following table shows how the HAL-defined power levels map to the hardware-specific power levels

HAL Power Level	Opamp Power Level	LPComp Power Level
CYHAL_POWER_LEVEL_HIGH	CY_CTB_POWER_HIGH	CY_LPCOMP_MODE_NORMAL
CYHAL_POWER_LEVEL_MEDIUM	CY_CTB_POWER_MEDIUM	CY_LPCOMP_MODE_LP
CYHAL_POWER_LEVEL_LOW	CY_CTB_POWER_LOW	CY_LPCOMP_MODE_ULP
CYHAL_POWER_LEVEL_DEFAULT	CY_CTB_POWER_MEDIUM	CY_LPCOMP_MODE_LP
