How do you read the injection channel on the ADC SAR Seq v2.50?

[PaDo_1228851]

I have the ADC SAR set up for channel 0 and the INJ channel.  

I can read channel 0 fine with this code:

ADC_StartConvert();

ADC_IsEndConversion( ADC_WAIT_FOR_RESULT );

data = ADC_GetResult16( 0 );

But the following doesn't work for the Injection Channel:

ADC_StartConvert();

ADC_EnableInjection();

ADC_IsEndConversion( ADC_WAIT_FOR_RESULT_INJECT );

data = ADC_GetResult16( ADC_SAR_INJ_RESULT_REG );

I can't find example code anywhere.  What am I doing wrong?  Thanks!

You can find channel injection in the Cypress stock example project ADC_SAR_Seq_DieTemp_PSoC401 (File->Code Example->P4200).

This code also worked for me:

ADC_SAR_SEQ_EnableInjection();

ADC_SAR_SEQ_StartConvert();

ADC_SAR_SEQ_IsEndConversion( ADS_SAR_SEQ_WAIT_FOR_RESULT_INJ );

uint16 data = ADC_SAR_INJ_RESULT_REG;
