Hi This is ben.
This device usesd to MP.
LM1972 connected to CPU. The purpose is for writing in register.
Then ,it's question.
For setting writing clock that the OK clock is 1.6MHz , the NG clock is 2.6MHz.
2.6MHz is first time is NG t , second time is OK for power on .
① 2.6MHz clock is ok clock?
② What reason first time is NG
③ detaseet p3 shows fclk is typical 3 and limit 2MHz, please OK clock range.
Thank you for your consideration.
