What is the BB_INT interrupt ?

[tam1111574]

Hi ESP32,
In my project I use ESP32 is a main processor, I use BLUETOOTH CLASSIC and configure it run in CPU0 and main loop in app_main.
In my project does not need interrupt but sometimes I detect a interrupt affect to the loop in app_main.
I get value of DPORT register DPORT_PRO_INTR_STATUS_0_REG and sometimes bit 2 of this register is set to 1.
I search in datasheet and BIT2 is PRO_BB_INT_MAP_REG but I don't know the mean and source of interrupt.
Can you show to me some information of source interrupt and how to disable it because I want loop main is highest priority ?

Thank and best regards

Bb is for baseband so something to do with the radio
