Introduction

This driver for Atmel® | SMART ARM®-based microcontrollers provides an interface for the configuration and management of the the Peripheral Direct Memory Access (DMA) Controller (PDC) module.

The PDC transfers data between on-chip serial peripherals and the on and/or off-chip memories. The link between the PDC and a serial peripheral is operated by the AHB to ABP bridge.

This module:

  • Performs transfers to/from APB communication serial peripherals

  • Supports half-duplex and full-duplex peripherals

Devices from the following series can use this module:

  • Atmel | SMART SAM3A

  • Atmel | SMART SAM3N

  • Atmel | SMART SAM3S

  • Atmel | SMART SAM3U

  • Atmel | SMART SAM3X

  • Atmel | SMART SAM4E

  • Atmel | SMART SAM4N

  • Atmel | SMART SAM4S

  • Atmel | SMART SAM G
