Flag signal: M1028
Explanation
1. D: the special D for update.
2. CANFLS can update the Special D command. When it executes in read only
mode, it sends equivalent message as CANRX to the slave and saves the slave
response to this particular Special D. When it executes in read/write mode, it
sends equivalent message as CANTX to the slave and saves this special D
value to the corresponding slave.
3. M1066 and M1067 are both 0. When reading is complete, M1066 will be 1 and
this value will write to the designated register if the slave replies an accurate
response. When slave replies a fault response then M1067 will be 0 and this
error message will be recorded to D1076~D1079.
