ZLG/CF躯动中间件简要说明 CF卡可以工作在 PC Card ATA 1/O模式(lO口模式)、 PC Card ATA Memory模式 ( MEMORY模式)、 True IDe模式。CF卡在 True Ide模式下工作时兼容IDE硬盘,并且需 用的IO引脚较少,因此推荐使用CF卡的 True IDE模式。 ZLG/CF驱动中间件是基于CF 卡 True IDE模式的驱动,同时兼容DE硬盘

第1章ZLG/CF驱动使用 1.1基于LPC2210的ZLG/CF驱动使用 CF卡有PC卡IO、 MEMORY及 True IDE等种模式 True,而 IDE模式兼容DE硬 盘,该模式比其它的两种模式更实用,是3种模式中使用较多的一种本节中描述CF卡在 True IDE模式下的应用
