Other Parts Discussed in Thread: TLV320DAC3100
Hi team,
I want to diagnose Reg.29 Overflow Flags and Reg.44 FAC Interrupt flags.
Could you advise the way to intentionally generate those flags in my board?

Hi, Shinji,
The Overflow flag is associated to a maximum level of the digital waveform. The TLV320DAC3100 full-scale level is reached at 0x7FFF (for 16-bits length). If you reach this level or apply a digital volume gain that surpasses this level, you should get an overflow event, that enables the overflow flag.
In case of the DAC Interrupt Flags, all of them are described in Table 6-61 ( http://www.ti.com/lit/ds/symlink/tlv320dac3100.pdf#page=71 ).
Please let me know if you have additional questions or comments on this.
Best regards,

Hi Luis,
Do you have an example of intentionally flag DAC Interrupt?

Hi, Shinji,
I quick test for this would be sending a constant data of 0x7FFFF (16-bit data length) from an audio precision tool and add some gain with page 0 / registers 65 and 66.
