Query regarding ADC's status and control registers

[vinayakwadkar]

Hi,

We are using NXP’s MKL17Z128VLH4 device in our application and we want to use its ADC.

In datasheet of KL17 family, we found that there two status and control registers - SC1A and SC1B.

In datasheet we also found the naming as SC1A-SC1n and SC1B-SC1n.

Since in ADC memory map of KL17 family, there are only two status and control registers ADC0_SC1A and ADC0_SC1B.

Could you please tell what does mean by SC1A-SC1n and SC1B-SC1n ? What is the significance of ‘n’ in SC1A-SC1n and SC1B-SC1n ?

Thanks and Regards,

Vinayak Wadkar

Hi Vinayak,

If you are using KL17, there are only two status and control registers ADC0_SC1A and ADC0_SC1B.

For some other Kinetis may have four status and control registers ADC_SC1A to ADC_SC1D(for example KM1x )

SC1A is used for both software and hardware trigger modes of operation.

The SC1B–SC1n registers indicate potentially multiple SC1 registers for use only in hardware trigger mode.(for the KL17 'SC1B–SC1n' means SC1B–SC1B, for KM1x 'SC1B–SC1n' means SC1B–SC1D)

SC1A-SC1n means all of the status and control registers.

SC1B-SC1n means all of the status and control registers except SC1A.

Best Regards,

Robin
