Hi NXP Support,

 

We are using the freescale microcontroller MC9S08PT8VLC to communicate with a Zigbee network. The communication with Zigbee is possible at 9600 baud rate. Could you please assist us on how we can set the baud rate of the chip. Below is a snippet of the code we are using to flash the MC. 

 

void PC_UART_Init(void)
{
SYS_SOPT2 &= (byte)(~(byte)(0x80U));

PORT_PTCOE = PORT_PTCOE & ((byte)(~(byte)(0x40U))) | (byte)(0x80U);
PORT_PTCIE = PORT_PTCIE & ((byte)(~(byte)(0x80U))) | (byte)(0x40U);
PORT_PTCD |= (byte)(0x80U);

SCI1_C1 = (byte)(0x00U);
SCI1_C3 = (byte)(0x00U);
SCI1_C2 = (byte)(0x00U);
SCI1_S2 = (byte)(0x00U);
#ifdef INTERNAL_CLOCK
SCI0_BDH = 0x00U;
SCI0_BDL =0xC3U; //9600
#endif
#ifdef EXTERNAL_CLOCK
SCI0_BDH = 0x00U;
SCI0_BDL = 0x34U; //9600
#endif

 

Please assist us how can we reset the baud rate of MC to 9600. Let us know in case you need any other information.
