BQ76952: bq76952 alert pin

Part Number: BQ76952

您好!

       我在使用BQ76952开发BMS时,想使用alert pin作为MCU的中断引脚,alert pin直接连接到MCU引脚,MCU有开启弱上拉。但是当Alert pin因警报触发高电平后,即使Alarm Status警报标志全部被清除,Alert pin始终保持高电压,这是什么原因?具体设置如下:

//#define ALERTPinConfig_Def 0x2A 
//#define ALERTPinConfig_Def 0x02 
#define ALERTPinConfig_Def 0x22

以上几个值都有试过

#define DefaultAlarmMask_Def 0xF87C 

Alarm Status警报发生后也有通过0x62命令写入读取值清除。
