Input parameters
Data is the 8-bit data to be transmitted.
Data is the 9-bit data to be transmitted.
UART_Address specifies the address
for the UART node.
Prescaler can be a value ranging from
0 to 128.
UART_FLAG specifies the UART
status flag to be checked. It can be:
Transmit data register empty flag
Transmission complete flag
Read data register not empty flag
Idle line detected flag
Overrun error flag
Noise error flag
Framing error flag
Parity error flag
Line break detection flag
Send break characters flag
UART_FLAG specifies the UART
status flag to be cleared.
