KEAZ family ADHWT availability.

Hi, Dear People,

I need to choose an MCU from the KEAZ###AVL family. I need an ADC conversion hardware trigger, synchronized with the FTM module. It is available, but on a particular MCUs. In the datasheet it's stated, that this is optional. Even more, in the RM (KEA128 Sub-Family Reference Manual, Rev. 2, July 2014), section 24.4.3 Hardware Trigger it's written: " ... This source is not available on all MCUs. See the module introduction for information on the ADHWT source specific to this MCU."

I have problem finding document(s) on the NXP site, that specifies which particular MCUs (part numbers) actually do have ADC hardware trigger implemented.

Please, help me. I'm lost.

Best regards to everyone. Take care.

Mun

Hi Muncho,

All KEA128 devices should have this function. Please refer to Table 3-1 in reference manual.

You can refer to this document to get how to trig ADC by PWM.
