Part Number: TDA4VM

Would you please explain the differences between MCU_PORz and MCU_RESETz pins? 

How these signals should be connected (from the power supply point of view)?

    Hello Lucio,

    The PORz signal is a "power on reset" and is required to be asserted during  power up and power down.  The MCU_RESETz signal is a warm reset.  It can optionally be used to partially reset the MCU domain while the supplies are active.

    You can refer to the TDA4VM EVM schematics for an example of how these should be connected.
