Detailed Description

DPSK3 uses one of the available on-chip Digital-to-Analog Converters (DAC) to generate a dynamic, analog output signal, which can be used for enhanced debugging of high-speed processes such as control output monitoring.

Note: The DAC output signal is buffered by utilizing one of the available on-chip operational amplifiers. Please refer to the Operational Amplifier Configuration section for details.

Function Documentation

◆ sysDacModule_Initialize()

uint16_t sysDacModule_Initialize ( void )

DAC Module Base Register Initialization.

Returns: unsigned integer; 0=failure; 1=success

This function initializes the DAC module base registers for being operated by the auxiliary oscillator at an input clock frequency of 500 MHz.

In this application the DAC is used to provide a constant reference voltage of VDD/2 = 1.65 V to the external current sense shunt amplifier devices. Neither, built-in comparator nor Pulse-Density Modulator (PDM) ramp generator are used.

◆ sysDacOutput_Initialize()

uint16_t sysDacOutput_Initialize	(	volatile uint16_t	dacInstance,
		volatile uint16_t	initValue
	)

Initializes a user specified DAC instance with DAC output enabled.

Parameters

dacInstance	Index of the selected DAC Instance (1=DAC1, 2=DAC2, etc.)
initValue	Integer value at startup of the DAC peripheral instance

Returns: unsigned integer (0=failure, 1=success)

This function clears all registers of the declared DAC instance and initializes the registers required by a static Digital-to-Analog Converter output with the given default values.

Note: The initialization function does not enable the DAC instance. Please use function sysDacOutput_Enable() to turn on the DAC instance at the appropriate time.
