mdot ATZ Reset command

[FARRUKH]

hello experts!

when I send ATZ command, mdot resets as it should be, but why it sends Low Output signal at nReset pin?
We have custom PCBs and microcontroller’s main board Reset pin (active low) is connected to mDot, when ATZ command is executed, master MCU (lpc) also resets,
I’ve tested nReset pin from logic analyzer and it indeed outputs a low signal,

As per manual, nReset is input with pull up resistor,

any clue?/help will be highly appreciated.
