Other Parts Discussed in Thread: BQ78350

LED相关的寄存器配置如下:

LCDEN=0

LEDMODE=1

LEDCHG=1

LEDRCA=1

LEDR=1

LED FLASH PERIOD=10240

LED BLINK PERIOD=10240

LED DELAY=100

LED HOLD TIME=4s

LED Thresh1=0%

LED Thresh2=20%

LED Thresh3=40%

LED Thresh4=60%

LED Thresh5=80%

但是,在boot的过程中,LED1~LED5可以常亮几秒钟。

这是啥问题呢?
