Enumeration Type Documentation

enum _cmp_status

Enumerator
kCMP_In0BiggerThanIn1	comparator input 0 is bigger than input 1
kCMP_In1BiggerThanIn0	comparator input 1 is bigger than input 0

enum cmp_interrupt_mask_t

Enumerator
kCMP_EdgeRising	Edge sensitive, falling edge.
kCMP_EdgeFalling	Edge sensitive, rising edge.
kCMP_EdgeRisingFalling	Edge sensitive, rising and falling edge.
kCMP_LevelLow	Level sensitive, low level.
kCMP_LevelHigh	Level sensitive, high level.

enum cmp_mode_t

Enumerator
kCMP_FastMode	Used in an active or deep sleep mode, this mode requires PMU bias enabled.
kCMP_LowpowerMode	Used for all power mode, doesn't require PMU bias enabled.

enum cmp_input_t

Enumerator
kCMP_InputAllExternal	Cmp input from two external source.
kCMP_InputOneExternalOneInternal	Cmp input from one external input and one internal voltage reference 0.8V.
