Hi, on TDA4 there are two reset input pins for MCU and Main domain. Would you please support me on answering the following questions:
MCU/Main_PORz is used for cold resets and MCU/Main_RESETz is used for warm resets.
- What is the expected electrical implementation between MCU/Main_PORz and MCU/Main_RESETz?
Currently, intended application is using only MCU/Main_PORz connected to TDA4, MCU/Main_RESETz pin is left unconnected. Is this an acceptable configuration?
Or should both signals, MCU/Main_PORz and MCU/Main_RESETz tied together to the Power supply PGOOD/Reset line?
- MCU_RESETz specifies that some TDA4 subparts are not being affected by the reset and other ones are partially reset.
What is the meaning of partially reset?
