TLV320AIC3100: Allowed AOSR values

Part Number: TLV320AIC3100

Hi,

I'm refactoring our TLV320AIC3100 driver and I noticed that Figure 7-13. Clock Distribution Tree on page 64 (SLAS667C) shows that AOSR can be set between 1 - 1024 but the actual register (page 0, register 20) seems to have options for values 256, 128, 64 & 32, and everything else reserved. Table 7-24. PLL Example Configurations on page 68 even shows AOSR being 104 on one of the configurations.

Is the AOSR value limited to 256, 128, 64 & 32 or not?

    Hi,

    You are right in your comment above.

    Some of these figures are generic figures as there are other devices with the same architecture which uses other range/configuration.

    The register table/page is what you should refer to as this is specific to the device.

    So to answer your question yes AOSR is limited to the above values.

    Regards.
