贵刊2001年第5期17页黎先生《长虹A6机芯为何出现“M”字符》一文中提到“M”字符出现后的种种症状,并有“翻查资料得知,惟有CPU和存贮器之间SCL、SDA总线不正常,机器误进入厂家维修调试状态”的叙述。但并非CPU与存贮器之间SCL、SDA I~2C总线异常。长虹A6机芯共采用了LC864512与LC864525两种CPU:前者对应的长虹掩膜后命名为CH04801;后者对应的长虹掩膜后命名为:CHT0403、CHT0405、CHT0408三种,两个CPU其对应引脚功能完全相同,
Mr. Li “Changhong A6 movement appeared” M “character” article mentions the “M” character after the emergence of a variety of symptoms, and “look up information that only the CPU and save Between the memory SCL, SDA bus is not normal, the machine enters the factory repair debugging state ”statement. But not between the CPU and memory SCL, SDA I ~ 2C bus is abnormal. Changhong A6 movement used a total of LC864512 and LC864525 two CPU: the former corresponds to Changhong mask named CH04801; the latter corresponding to Changhong mask named: CHT0403, CHT0405, CHT0408 three, two CPU corresponding Foot function exactly the same,
