Uart .C; Delay_Try Function - Fujitsu MB2146-450-E Setup Manual

4.2.8 UART .c

In this function, the MCU works in an asynchronous mode. The baud rate is generated by a
dedicated baud rate generator. In the EV-Board sample code the baud rate is 9600.
Following table describes the LCD library:
Function Name
void UART_init (void)
void UART_sendbyte (char ch)
__interrupt void UART_REC_INTER(void)
Following table describes how to use these functions.
Type
UART_init();
Send data
UART_sendbyte(0x55);
Receive data UART_init();

4.2.9 delay_try Function

In this project, some instruction needs to be delayed, so the delay function must be defined
before using these C files. Following code is the delay_try function.
void delay_try(unsigned char Dat)
{
unsigned char i,j;
for(i=0;i<255;i++)
{
for(j=0;j<Dat;j++)
{
}
}
}
