void Uart_Init(void)
{
P1M1 = 0xFE; // Configure P1.0 (TxD) as Output (UART0)

BRGR0_0 = 0x70; // 9600 baud, 8 bit, no parity, 1 stop bit
BRGR1_0 = 0x01;
BRGCON_0 = 0x03;
S0CON = 0x52; // initialize UART 0
}

static void ua_outchar(unsigned char c)

while(!TI_0);
S0BUF = c;
TI_0 = 0;
}

void PrintString(const unsigned char *s)

AUXR1 |= 0x80;

Uart_Init();
ES = 1;
EA = 1;

ua_outchar(0x61);
// PrintString("Hello World\n");
while(1);
}

above is the simple code i am using to print on to hyper terminal. Problem i am getting is if i send 0x61('a')(=97) it displays symbol of beta(=225), basically it is difference of 128 means my sign bit is set to one, it happens with all the characters,

Other things to note is this code works fine when i use LPC952 microcontroller, but it gives me above error once i start working with LPC954( LPC952 with 16 kb flash, instead of 8 kb),

am i missing something?

Thanks,
