Time Addition
All the S1, S2 and D occupies 3 components respectively
S1 : the summand of the time combination
S2 : the addend of the time combination
D : the sum of the time combination
The designated time combination of the summand will be added to the designated time combination and
the combination of the sum will be stored at the assigned registers .
When X20 = “ON”, the instruction will be performed.
D0 = 8 (Hour)
D1 = 30 (Minute)
D2 = 0 (Second)
D10 = 6 (Hour)
D11 = 35 (Minute)
D12 = 30 (Second)
D20 = 15 (Hour)
D21 = 5 (Minute)
D22 = 30 (Second)
