Hello all, 

                        So i have made an integer array of size 36. and I have been trying to send the values across. But it is not happening. It is sending only 16 bytes of data. I have configured the tx as per below:

/* Enable Transmit FIFO */
SciaRegs.SCIFFTX.bit.TXFIFOXRESET =1U;

/* Force a transmit ISR */
SciaRegs.SCIFFTX.bit.TXFFINTCLR = 1U ;
  

Below is the stream I am trying to send. 

Uint16 transmitBuffer[36];

transmitBuffer[0] = '$';
/* PAN feedback */
/* Function code*/
transmitBuffer[1] = '3';

transmitBuffer[2] = '4';
transmitBuffer[3] = '5';
transmitBuffer[4] = '6';
transmitBuffer[5] = '7';
transmitBuffer[6] = '8';
transmitBuffer[7] = '9';
transmitBuffer[8] = 65;
transmitBuffer[9] = 66;
transmitBuffer[10] = 67;
transmitBuffer[11] = 68;
transmitBuffer[12] = 69;
transmitBuffer[13] = 70;
transmitBuffer[14] = 71;
transmitBuffer[15] = 72;
transmitBuffer[16] = 73;
transmitBuffer[17] = 74;
transmitBuffer[18] = 75;
transmitBuffer[19] = 76;
transmitBuffer[20] = 77;
transmitBuffer[21] = 78;
transmitBuffer[22] = 79;
transmitBuffer[23] = 80;
transmitBuffer[24] = 81;
transmitBuffer[25] = 82;
transmitBuffer[26] = 83;
transmitBuffer[27] = 84;
transmitBuffer[28] = 85;
transmitBuffer[29] = 86;
transmitBuffer[30] = 87;
transmitBuffer[31] = 88;
transmitBuffer[32] = 89;
transmitBuffer[33] = 90;
transmitBuffer[34] = 97;
transmitBuffer[35] = 98;
