see MSP430 coding example below.

   uint8_t parity = ;

   uint8_t index = ;

   //flag

   gMUXTask.responseData[index++] = MUX_DATA_BIT_LOW;

   //dirty

   gMUXTask.responseData[index++] = gDeviceStatus.responseStatus.dirty;

   parity += gDeviceStatus.responseStatus.dirty;

   //smoke alarm

   gMUXTask.responseData[index++] = gDeviceStatus.responseStatus.smokeAlarm;

   parity += gDeviceStatus.responseStatus.smokeAlarm;

   //high temperature

   gMUXTask.responseData[index++] = gDeviceStatus.responseStatus.highTemperature;

   parity += gDeviceStatus.responseStatus.highTemperature;

   //low temperature

   gMUXTask.responseData[index++] = gDeviceStatus.responseStatus.lowTemperature;

   parity += gDeviceStatus.responseStatus.lowTemperature;

   //miss Head

   gMUXTask.responseData[index++] = gDeviceStatus.responseStatus.missHead;

   parity += gDeviceStatus.responseStatus.missHead;

   //parity

   gMUXTask.responseData[index++] = CalcParity(isOddAlgorithm(false), parity);

   //outputState

   gMUXTask.responseData[index++] = MUX_DATA_BIT_LOW;

The ASM code generated is below, it is around 120bytes.

Another example here,

   uint8_t* p = gMUXTask.responseData;

   *p++ = MUX_DATA_BIT_LOW;

   //dirty

   *p++ = gDeviceStatus.responseStatus.dirty;

   parity += gDeviceStatus.responseStatus.dirty;

   //smoke alarm

   *p++ = gDeviceStatus.responseStatus.smokeAlarm;

   parity += gDeviceStatus.responseStatus.smokeAlarm;

   //high temperature

   *p++ = gDeviceStatus.responseStatus.highTemperature;

   parity += gDeviceStatus.responseStatus.highTemperature;

   //low temperature

   *p++ = gDeviceStatus.responseStatus.lowTemperature;

   parity += gDeviceStatus.responseStatus.lowTemperature;

   //miss Head

   *p++ = gDeviceStatus.responseStatus.missHead;

   parity += gDeviceStatus.responseStatus.missHead;

   //parity

   *p++ = CalcParity(isOddAlgorithm(false), parity);

   //outputState

   *p++ = MUX_DATA_BIT_LOW;

The ASM code generated, it is about 106 bytes.
