    • A microcomputer is provided having a memory card interface capable of correctly latching data even when a card such as an MMC card is connected thereto. In the microcomputer having an interface with an external device such as a memory card, the interface unit is provided with an output driver connected to an external terminal for outputting a clock signal to output the clock signal and with an equivalent load circuit capable of imparting, to the clock signal extracted from an arbitrary position in a stage previous to the output driver in a clock signal path, delay equivalent to delay resulting from an external load connected to the external terminal in order to generate a clock signal for latching data inputted from the memory card.
    • 即使当诸如MMC卡的卡连接到其上时,也提供具有能够正确地锁存数据的存储卡接口的微型计算机。 在具有与诸如存储卡的外部设备的接口的微型计算机中,接口单元设置有连接到外部端子的输出驱动器,用于输出时钟信号以输出时钟信号,并且具有能够传递时钟信号的等效负载电路, 与从时钟信号路径中的输出驱动器之前的级中的任意位置提取的时钟信号相当于连接到外部端子的外部负载引起的延迟的延迟,以便产生用于锁存从外部端子输入的数据的时钟信号 存储卡。
