The PCI_MT function provides a solution for integrating 32-bit PCI peripheral devices,and is fully tested to meet the requirements of the PCI specification. It is optimized for the AT40K20 device, enabling the designers to focus efforts on the custom logic surrounding the PCI interface. The PCI_MT macro is intended for use in Atmel’s AT40K devices with remaining logic resources available for user-defined local side (DMA control engine) customization.
