Embedded FW for ATTiny441 / ATtiny841a UART brigde from 9bit to 8bit

I need to have an ATTiny441 or ATTiny841 processor based project which has 2x UART inside to convert a data stream coming to one UART at 9bit, odd parity and 2 stop bit (9O2) to output on other UART at 8bit, odd parity, 2 stop bits (8O2). 9th bit is discharged and not in use (lost on transition)

Baudrate on both UARTs is 9600

Data coming in is TTL level and data goingout is TTL level.

Also there must be presented schematics how to connect all, how to program it and which oscillator to be used in final HW design.
