Simply read the reg 0x02h input data, take control according to the following diagram.

FW flow is: CS set low - > set data0-7 to output - > ALE set high - >dataset 0-7 = 0x02 - > ALE set low - data > set 0-7 to input - > RD set low - > read data 0-7 - > RD set high - >CS set high.

The logical analyzer observed that the data pin did not seem to change during ALE (keep low), and saw that ALE and CS pins would suddenly jump high and drop immediately.

(SEL is direct grounding, ALE is push-pull and everything else is set to open-drian, but it doesn't seem to affect the result)

Which part of the circuit should I pay attention to or correct? Thank you.

I have a question about IPM 3-phase Inverter Simulator.

The frequency input to System Frequency is recognized as the frequency of the current waveform output by the inverter, is it correct?

The frequency f is an understanding obtained by calculating backwards from the following equation.

Ns＝(120*f)/P

*Ns: Motor speed [rpm], P: Motor pole number
