 * Parallel Master Port Write a block of bytes (8-bit)
 *
 * Function:        void PMPMasterWriteByteBlock(unsigned int, unsigned int,
 *                                               unsigned char*)
 *
 * PreCondition:    None
 *
 * Input:           Argument #1 (unsigned int) addrs = starting address
 *                  Argument #2 (unsigned int) bytes = number of bytes to read
 *                  Argument #3 (unsigned char*) _pSrc = byte data destination
 *
 * Output:          None
 *
 * Example:         PMPMasterWriteByteBlock(0x8000, 0x800, &myArray);
 *
 * Overview:        Writes N bytes (argument #2) starting at location specified
 *                  in (argument #1), from the destination specified by
 *                  byte pointer (argum.ent #3)
 *
 * Note:            Use in MASTER mode 1 or 2, MODE[1:0] = 10, 11
