我在使用TJA1055时，碰到了INH引脚异常拉高的问题：
正常情况下，TJA1055进入sleep模式时，INH引脚会被拉低。我现在在使用时发现，通过拉低EN和STB进入sleep模式后，过了大概900ms左右，INH引脚又变为了高电平，此时EN和STB脚都为低。请问这种情况是什么原因导致的？是TJA1055在进入sleep模式时有特殊请求吗（goto sleep command命令已加入）。
非常感谢！！！
hello，When using TJA1055, I encountered the problem of abnormal high INH pin:
As everyone knows,When TJA1055 enters sleep mode, INH pin will be pulled down.But now I find that after TJA1055 enters sleep mode, INH is pulled down again 900 ms and then raised again.I have carried out the relevant operation according to the data manual,I don't know why it happened.
