Response frame when you send a command for setting a parameter
When the data cannot be stored due to the attempt to store data while the unit is
running, the setting data will not be stored and the original data will be responded.
All of 16-bit register is 1. 0xffff
The exclusive OR of 16-bit register and 8-bit register.
Shift right side 1bit a 16-bit register
If the result of step 3 is 1, exclusive OR 16-bit register and 0xa001.
Execute 8 times step 3 and step 4.
Execute step 2~6 until data completion
Exchange the step 6 result of higher 8bit and lower 8bit.
