uint32_t ui32Ref)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_COMPARATORTABLE is an array of pointers located at ROM_APITABLE[6].
ROM_ComparatorRefSet is a function pointer located at ROM_COMPARATORTABLE[2].
Parameters:
ui32Base is the base address of the comparator module.
ui32Ref is the desired reference voltage.
