We use TPS6594133ARWERQ1,the internal watchdog is enabled upon power-up of the PMIC.
According to the EVM default configuration, the long window is 13 minutes.
(1) Is the first long window after PMIC power-on always limited to 13 minutes? If so, 13 minutes is sufficient to support the entire power-up process of the TDA4. But is 13 minutes too long? If there is a fault when TDA4 is powered on, the watchdog will report the fault only after 13 minutes.
(2) After PMIC is powered on, can TDA4 directly modify the first long window through I2C? Or does it require a dog-feeding operation to be performed first before modifying the duration of the long window?
