Questions about TPS65930 interrupt ability

Other Parts Discussed in Thread: TPS65930

In TPS65930 TRM 4.4 Functional Description:

It says "Ability of a pending event (which can arrive during software latency) to generate an interrupt to the host
or disable the plug/unplug feature"

1) Does it means that it has the ability of generating an interrupt when an interrupt is processing??

2) What is the plug/unplug feature?

thanks.

    Hi Jack,

    1. This device can store a pending interrupt. So, in case the current interrupt is still active and there is a second interrupt then this second one can be in the queue and will generate an interrupt to host when the first one clears. Refer section 4.4.2.3

    2. Plug/unplug refer to events for USB/VAC plug/unplug. These can be diabled by masking the appropriate bits in the IMR register.

    Hope this helps.

     

    Regards,

    Gandhar.

    Thanks Gandhar.

    Can I consider that if the pending interrupt is caused by an plug event, it will disable the plug/unplug interrupt of that subchip? And the disabled interrupt will be enabled again as soon as the pending interrupt is acknowledeged?
