DVP-04AD is connected to the right side of DVP15MC11T. When FRM1_Ex changes from FALSE to
TRUE and FRM1_Bsy and FRM1_Act change to TRUE simultaneously, FROM instruction starts to
execute. When FRM1_Done changes to TRUE, the instruction execution is finished. The values read
from CR2, CR3, CR4 and CR5 are stored in the four elements FRM1_DP[1], FRM1_DP[2], FRM1_DP[3]
and FRM1_DP[4] of the FRM1_DP array.
