Hardware Abstraction Layer (HAL)

On CAT1 & CAT2, the comparator driver can use either of two underlying hardware blocks:
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.
The following table shows how the HAL-defined power levels map to the hardware-specific power levels. For the LPComp, some levels are named differently between CAT1 & CAT2. In this case, the differences are in brackets, with the first item being for CAT1 and the second for CAT2.
| HAL Power Level | Opamp Power Level | LPComp Power Level |
|---|---|---|
| CYHAL_POWER_LEVEL_HIGH | CY_CTB_POWER_HIGH | CY_LPCOMP_MODE_[NORMAL/FAST] |
| CYHAL_POWER_LEVEL_MEDIUM | CY_CTB_POWER_MEDIUM | CY_LPCOMP_MODE_[LP/SLOW] |
| CYHAL_POWER_LEVEL_LOW | CY_CTB_POWER_LOW | CY_LPCOMP_MODE_ULP |
| CYHAL_POWER_LEVEL_DEFAULT | CY_CTB_POWER_MEDIUM | CY_LPCOMP_MODE_[LP/SLOW] |
