Help¶

This enables DMA driven transactions for the I2C peripheral. DMA driven mode requires fewer interrupts to handle the transaction and ensures that high speed modes are not delayed by data reloading.

Direct dependencies¶

I2C_SAM0 && I2C

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
