In the K22P144M120SF5V2RM.pdf file on Kinetis K22 Sub-Family Reference Manual, the

FTM channel control register, FTMx_CnSC, has two bits, CHIE and DMA, section 38.3.6.

 

CHIE - 1 Enables channel interrupts

DMA - 1 Enable DMA transfer

 

It appears to enable a DMA transfer from an FTM channel event, both the CHIE and DMA bits must be be on.

 

The documentation does not make this clear.

 

Is this a property of all peripherals or just the FTM?
