2. Register & Data
Instruction Format Code Cycle Bytes Instruction Description
ADDC Rn, Data ﹔
6n 1 2
The value of Rn adds Data,only set Carry but don’t
change the value of Rn. ( Rn + Data ÎC=?)
ADDD Rn, Data ﹔
7n 1 2 Rn ÍRn + Data
ANDD Rn, Data ﹔
4n 1 2
The value of Rn logical AND Data,set the solution
to Rn. ( Rn Í Rn AND Data)
MOVD Rn, Data ﹔
5n 1 2 set Rn Í Data.
SUBDC Rn, Data ﹔
En 1 2
The value of Rn subduct Data, only return Carry
but don’t change the value of Rn.(Rn-DataÎC?)
SUBD Rn, Data ﹔
Fn 1 2 Rn Í Rn - Data
PS :
(1). Rn ﹕Number of Register,e.g. R3；n = 0 ~ 15.
(2). Data ﹕a decimal value during 0 ~ 255.
