This option enables the ADC driver for Infineon PSOC C3
HPPASS (High Performance Programmable Analog Sub-System) SAR ADC.

The HPPASS SAR ADC provides 12-bit analog-to-digital
conversion capabilities

help
Infineon HPPASS SAR ADC driver initialization priority.
This should be higher than the HPPASS_ANALOG_INIT_PRIORITY
to ensure the analog subsystem is initialized first.
