过程描述的不是很详细，比如HRESET_B刚开始是输出，然后变成输入。 输出的时间是多少呢？
我的如下方案：用复位芯片延时200ms，同时驱动PORESET_B和HRESET_B，LS1043是否能正常启动？
Please refer LS1043A Reference Manual 4.4.1 Power-on reset sequence, The device stops driving HRESET_B at step 15. The timing of HRESET_B depends on the steps before the step 15. please confirm you application meet the sequence.
