Reserved registers in script file. (TLV320DAC3101)

Other Parts Discussed in Thread: TLV320DAC3101

Hello,

 

My customer use TLV320DAC3101 and will refer DAC3101_USB_Init(script file) in codec control software for initialization.

Regarding to reserved registers, we have a question.

(Question.)

1) In script file, the data is written in some reserved registers.

 

･page0,address: 0x12-0x15

w 30 12 84

> 84

#                       DOSR = 128, DOSR(9:8) = 0

> 00

#                                    DOSR(7:0) = 128

> 80

 

･page1,address: 0x31

w 30 31 00

 

But according to datasheet, it is not allowed to write to reserved registers(0x0f-0x18).

Should we set same data in these registers like same this script file?

 

Regards,

    Hi, Tao_2199,

    Welcome to E2E and thank you for your interest in our products!

    This script has a typo and the reserved registers must be removed as you mentioned. We don't recommend to write on the reserved registers. Please ensure that the registers that the script configures are according to the datasheet specifications.

    Please let me know if you have more questions or comments.

    Best regards,
    Luis Fernando Rodríguez S.

    Hi Luis-san,

    Sorry to interrupt you, but I want you to confirm about below.

    According to your comnent, "DAC3101_USB_Init" is NOT for only DAC3101.(It seems that this is included setting of other device as well.)
    So, we want the document which is described "initialization sequence" of DAC3101.
    Is there any application note ?

    Best Regards,
    Machida
