Dear Sir 

 

I'm developing a CAR AMP. which use MCU+ ADAU1452. this is the first time use ADAU1452 nd have some question on selfboot and safeload(to avoid pop noise)

 

1. How to use eeprom for selfboot of ADAU1452? How to set chip address of SPI?

2. How to use safeload to send command from MCU to ADAU1452? I have use I2C decoder to watch the command code to ADAU1452 but the command code are different between Sigmastudio USB KIT to EV Board and MCU to ADAU1452 from Existed Machine. Both of them are use same DSP BLOCK.

I attached the command code below:

Param EQ (Sigmastudio USB KITto EV BOARD)

0x01,0x64, xxxxxxxxxx (continue 20bytes eq data)

0x01,0x69,0x00,0x00,xx,xx (first address code),0x00,0x00,0x00,0x05

 

Param EQ (MCU to ADAU1452)

0x01,0x18, xxxxxxxxxx (continue 20bytes eq data)

0x01,0x1d,0x00,0x00,xx,xx (first address code)

0x00,0x1e,0x00,0x05

 

Phase block (Sigmastudio USB KITto EV BOARD)

0x01,0x64, 0x00,0x00,0x00,0x01

0x01,0x69,0x00,0x00,xx,xx (address code),0x00,0x00,0x00,0x01

 

Phase block (MCU to ADAU1452)

0x01,0x18, 0x00,0x00,0x00,0x01

0x01,0x1d,0x00,0x00,xx,xx (first address code)

0x00,0x1e,0x00,0x01

 

My question might not clear, if you need any information please feel free to contact with me. Thank you.
