| 思睿逻辑 EP93xx 模拟数字转换器驱动 |
| ================================== |
| |
| 1. 概述 |
| ======= |
| |
| 该驱动同时适用于具有5通道模拟数字转换器的低端 (EP9301, Ep9302) 设备和10通道 |
| 触摸屏/模拟数字转换器的高端设备(EP9307, EP9312, EP9315)。 |
| |
| 2. 通道编号 |
| =========== |
| |
| EP9301和EP9302数据表定义了通道0..4的编号方案。虽然EP9307, EP9312和EP9315多 |
| 了3个通道（一共8个），但是编号并没有定义。所以说最后三个通道是随机编号的。 |
| |
