    • A data transfer controller for controlling DMA data transfer between a memory area and a peripheral unit. The data transfer controller has a first register which stores address information relative to a predetermined address of the memory area. A DMA control unit uses the first register and a second register to perform the DMA data transfer between the memory area and the peripheral unit. The data transfer controller also has a third register for storing data used for accessing the memory area of the DMA transfer. An updater is used to update the contents of the third register whenever a memory access uses the third register and is different from a memory access associated with data transfer between the memory area and the peripheral unit. Finally, a counter changes the contents of the third register in one direction whenever the data transfer between the memory area and the peripheral unit is performed. The counter changes the contents of the third register in an opposite direction whenever memory access using the third register is performed.
    • 一种数据传输控制器,用于控制存储区和外设之间的DMA数据传输。 数据传输控制器具有第一寄存器,其存储相对于存储器区域的预定地址的地址信息。 DMA控制单元使用第一寄存器和第二寄存器来执行存储器区域和外围单元之间的DMA数据传输。 数据传输控制器还具有用于存储用于访问DMA传输的存储区域的数据的第三寄存器。 只要存储器访问使用第三寄存器并且与存储器区域和外围单元之间的数据传输相关联的存储器访问不同,更新器被用于更新第三寄存器的内容。 最后,每当执行存储器区域和外围单元之间的数据传输时,计数器在一个方向上改变第三寄存器的内容。 当执行使用第三个寄存器的存储器访问时,计数器以相反的方向改变第三寄存器的内容。
