aP89170 serial mode interface is not working, is anybody sucessfully interfaced aP89170 in serial mode with MCU?
 

It is an I2C device. Have you written I2C code for communicating with the device (APLUS) ? Post code and datasheet of device. I might be wrong. It might be a SPI device. Try Software SPI code and make sure if LSB gows first ot MSB.

I tried but no result. is there any other suggestion?
 

It is an SPI device. The datasheet mentions about device read and write operations. Please read it and try.
 

problem solved, issue is on chip power on command code, there are two command code for power on chip, 0xC5 worked for me instead 0x8D.
