Texas Instruments TMS320C6000 manual AD535writeReg, AD535writeHwi

AD535_writeReg

AD535_writeHwi	Writes value to input of DAC
Function		void AD535_writeHwi(
		AD535_Handle		hAD535,
		int val
	);
Arguments		hAD535	Handle to codec channel, see AD535_open()
		val	Value to be written to DAC.
Return Value		none
Description		Writes value to the input of the DAC. Unlike the AD535_write API, it
		does not use polling to establish that the McBSP is ready to write another
		sample. Rather, it requires the McBSP to already be ready. In other words,
		the AD535_writeHwi is for use within an Interrupt Service Routine. The
		face that you arrived at an McBSP transmit ISR signifies that the McBSP
		is ready with another sample.
Example		/* The function is included in the ISR associated to
		McBSP receive event XEVT */
		void AD535_writeIsr(){
		Uint val = 0x0066;
		AD535_writeHwi(hAD535,val);
	}
	Writes value to specified control register
AD535_writeReg
Function		void AD535_writeReg(
		AD535_Handle		hAD535,
		AD535_Reg		ad535Register,
		Uint32		val
	);
Arguments		hAD535		Handle to codec channel, see AD535_open()
		ad535Register		Control register enumeration:
				- AD535_REG_CTRL0
				- AD535_REG_CTRL1
				- AD535_REG_CTRL2
				- AD535_REG_CTRL3
				- AD535_REG_CTRL4
				- AD535_REG_CTRL5
		val		Value to be written to specified register
Return Value		none
