Macro Definition Documentation

#define PMC_GetLVDF

(

)

This macro returns LVDF status.

Returns

true (non-zero) internal supply voltage falls below the selected internal monitor trip point (VLVD),

false normal operation.

Note

Implemented as an inline macro.

#define PMC_GetLVWF

(

)

This macro returns LVWF status.

Returns

true (non-zero) internal supply voltage falls below the selected internal monitor trip point (VLVW),

false normal operation.

Note

Implemented as an inline macro.

#define PMC_GetREGONS

(

)

This macro returns regulator status (PMC_REGSC_REGSON).

Returns

true (non-zero) regulator is in stop regulation or in transition to/from it,

false regulator is in run regulation.

Note

Implemented as an inline macro.

#define PMC_GetACKISO

(

)

This macro returns state indicating whether certain peripherals and the I/O pads are in a latched state as a result of having been in a VLLS mode. Writing one to this bit when it is set releases the I/O pads and certain peripherals to their normal run mode state.

Returns

true (non-zero) peripherals and I/O pads are in an isolated and latched state,

false peripherals and I/O pads are in normal run state.

Note

Implemented as an inline macro.

PMC_SetACKISO

#define PMC_SetACKISO

(

)

This macro releases I/O held state (the I/O states are held on a wakeup event until the wakeup has been acknowledged via a write to ACKISO bit).

Note

Implemented as an inline macro.

See also

PMC_GetACKISO

#define PMC_SetBGEN

(

)

This macro enables bandgap reference in VLPx and VLLSx modes.

Note

Implemented as an inline macro.

See also

PMC_ClrBGEN

#define PMC_ClrBGEN

(

)

This macro disables bandgap reference in VLPx and VLLSx modes.

Note

Implemented as an inline macro.

See also

PMC_SetBGEN

#define PMC_SetBGBE

(

)

This macro enables bandgap buffer.

Note

Implemented as an inline macro.

Warning

Enable bandgap buffer if you want to measure bandgap voltage by ADC or using 1.0V Internal bandgap as the ADC reference.

See also

PMC_ClrBGBE

#define PMC_ClrBGBE

(

)

This macro disables bandgap buffer.

Note

Implemented as an inline macro. This function also switches bandgap buffer to low drive mode.

See also

PMC_SetBGBE

#define PMC_Init	(		cfg1,
			cfg2,
			ip,
			callback
	)

This function initializes Power Management Controller (PMC) block. Function installs callback function for interrupt vector 22 (PMC).

Parameters

cfg1	Select one of the PMC Configuration Structures.
cfg2	Select one of the PMC Internal Voltage Regulator Configuration Structures.
ip	Select one of the ARM Cortex-M0+ Interrupt Priority Levels.
callback	Pointer to the PMC Callback Function.

Note

Implemented as a function call.
