I would like to confirm the role of the following communication formats.
1.QSPI
It is a recognition that the application created by the user is loaded, but how do you write the application loaded from CP? (U1 and the personal computer seem to have no contact at all.)
2.UART
Are you connected to U7?
Is it okay to recognize that U7 is used to check the operation of the application loaded in U2?
3.I2C
I am connected to U4, but is it okay to think that this is responsible for sending a reset signal to U4 when the power IC sends an error signal?
Also, is I2C used only to control the PMIC?
