IT8613E,Super I/O,逻辑设备，温度，电压寄存器数据更改，风扇，看门狗

news/2024/12/2 15:33:28/

IT8613E,温度，电压，风扇，逻辑设备号，寄存器数据更改看门狗代码备份。
命令行输入分以下几种情况：
①mySIO.efi输出当前的温度，电压，风扇转速
②mySIO.efi Xd "X"表示逻辑设备号，输出LDN=X时的寄存器列表
③mySIO.efi W X,这里执行看门狗功能，X表示秒数，代码设定1-9秒
④mySIO.efi Xd offset value,执行LDN=x时，地址offset寄存器的值设置为value
⑤mySIO.efi G X，风扇调速，X表示档位，有0,1,2三个档位，0表示停止，有个bug，执行完毕会输出一个风扇转速值，这个值是更改前的值。
⑥mySIO.efi GP10 I/O N/Y H/L，其中GP10表示GPIO10，可更改，第二个表示输入模式还是输出模式，Ｎ／Ｙ选择不反转/反转，H/L表示高/低电平.
