You know that ATmega32 supports Universal Asynchronous Receiver/Transmitter.

with pins : RXD & TXD

But it doesn't support Universal synchronous Receiver/Transmitter.

with pins : RXD/TXD & CLOCK

What should I do to be able to use both the USRT and UART interfaces on my microcontroller?

ATMega32 has one USART that works either in synchronous (RXD,TXD,XCK) or asynchronous (RXD,TXD) mode, but not both.

If you need second synchronous port, use SPI.
