Using Built in Baud rate generator on 89C669

Dear Andy,

I am also facing the same problem with 89C669. Do you have any solution for this? Please help me.

Thanks in advance.

My Code for Using Built in baud generator for both serial ports. Hope it helps :-

// initialise on board comms
BRGCON = 0;
//12 MHz
BRGR0 = 0xD2;
BRGR1 = 0x4; //Set To Baud rate generator to 9600
//11.0592 MHz
// BRGR0 = 0x7E;
// BRGR1 = 0x4; //Set To Baud rate generator to 9600

BRGCON = 3;
T2CON = 0x30; // RCLK=1. TCLK = 1, Timer 2 Disabled


SCON = 0x50; // SCON: mode 1, 8-bit UART, enable rcvr
REN_0 = 1;
ES0 = 1; // Enable Interrupt
TI_0 = 1; // TI: set TI to send first char of UART

//Uart 2
S1CON = 0x50; // SCON: mode 1, 8-bit UART, enable rcvr
REN_1 = 1;
ES1 = 1;
TI_1 = 1; // TI: set TI to send first char of UART

Hi

#define Kristall        19660800
#define Baud            19200
#define	BRATE		(Kristall/Baud)-16

void    StartRS232(void)
{
BRGR0 = BRATE & 0x00ff;
BRGR1 = (BRATE & 0xff00) / 256;
SM0_0 = 0;
SM1_0 = 1;
SM0_1 = 0;
SM1_1 = 1;
RCLK = 1;
TCLK = 1;
BRGCON = 0x03;
REN_0 = 1;
REN_1 = 1;
TI_0 = 1;
TI_1 = 1;
}
