TLV320AIC3100: EVM check

Part Number: TLV320AIC3100


Hi team,

Could you help check below?

Set below registers and connect J4 to headphones and then test TP13.

But it looks like it's insensitive. 

Could you help check below settings are correct or not?

Thank you!

P0R48 = 0x80   (INT1 Control Register -> Headset-insertion detect interrupt)

P0R51 = 0x14  (GPIO1 In/Out Pin Control -> INT1 output)

P0R67 = 0x80  (Headset detection -> enabled)

    Hi,

    Here are the steps:

    • Enable headset detection P0R67=0x80
    • Enable INT1 for headset detection  P0R48=0x80
    • Enable GPIO1 for INT1 P0R51=0x14
    • Read INT Flag P0R44
    • Insert/remove the headset

    Basically read the flag once before inserting or removing the headset then you will see the interrupt on GPIO1.

    Regards.
