R[z] ( = XOR)Mikroone - Online Help
Operating Mode
1. XOR R[x],R[y],R[z]
R[x] := R[y] R[z] ( = XOR)
2. OR R[x],R[y],R[z]
R[x] := R[y] + R[z] (+ = OR)
3. AND R[x],R[y],R[z]
R[x] := R[y] * R[z] (* = AND)
PC := PC + 1
Description
Bitwise exclusiv - OR, OR, AND with content of registers R[y] and R[z].
Result is saved to R[x].
Status Register
Zero - Bit := 1 if all Bits of R[y] are 0 after operation
