TPS65219: Keep Error Flags on toggle Enable?

Motoyasu Hattori

Part Number: TPS65219


Hi,

I have one question related to INT register.

 

When error is occurred, TPS65219 set appropriate bits on INT_xxx registers (such as INT_LDO_1_2, INT_BUCK_1_2 etc.).

When EN pins is toggled (ON->OFF->ON,,,), are "bits of these INT_xxx registers" clear or kept?

Please advise us.

Thanks and best regards,
M.HATTORI.

    Hi,

    Thank You for using E2E. The interrupts stay in the registers until a W1C (write 1b to clear) is executed. The data sheet capture below shows an example of interrupt fields that require writing a 1b to clear. Please let us know if this answers your question.

    Thanks,

    Brenda
