You need to connect the UART to an RS232 transceiver which is then connected to your PC COM port.
You also need to put the part into ISP mode which requires pulling some pins. See the user manual from NXP for details.

Hi good day everybody,
Would you please let me know how can I make copy of this controller and saved to other micro controller?

You need to read out the contents of flash to a hex file in Flash Magic, then program that hex file into the other device.

Note - you need to program into the same part number. Also if the device is locked then you won't be able to read the flash.
