I found that ADM2483 has a PV input pin and ADM809 is recommended to drive this
pin. If I want to use this function, can I tie it to microcontroller to temporary isolate TXD/RXD pins from RS-485 traffic?

Hi Zeliboba,
The PV pin can be used for ADM2483 power up/power down only.
The ADM809 can be used to monitor the power supply voltage in microprocessor systems.
It is primarily used for power on reset.
Best regards,
Richard
