+The purpose of this test is to validate basic UART driver functions,
+that are not tested elsewhere.
+UART interrupt mode is used for the tests purpose.
+
+Hardware setup required for these tests:
+For single uart conviguration - UART0 TX connected to RX and CTS to RTS
+For dual uart configuratiom - UART0 and UART1 TXs and RXs cross-connected
+
+These test cases cover:
+- UART configuration,
+- UART error check,
+- UART callback setup,
+- Dual UART transmission with matched and mismatched configurations
