8.5.5 Logic action instructions
= AND = OR = XOR
To perform logic operations: AND, OR and XOR between register contents or between a register
content and a number. The result is always stored in a register.
Its programming format is:
Registers (R1/559) or numbers expressed in decimal, hexadecimal or binary format can be defined
as first or second operand.
The destination register indicates where the result of the operation will be deposited and will be
defined by means of a register (R1/559).
The mark M2003 is called zero flag and indicates whether the result of an AND, OR, XOR, operation
equals zero, in which case it follows that M2003=1.
Examples with: R200 = B1001 0010
R201 = B0100 0101
= RR = RL
Used to rotate registers clockwise (RR) or counterclockwise (RL). There are two types of rotations:
type 1 (RR1 or RL1) and type 2 (RR2 or RL2).
Rotation type 1 (RL1 or RR1):
It inserts a "0" at the least significant bit (RL1) or at the most significant bit (RR1), pushing the other
bits of the register. The value of the last bit disappears.
Rotation type 2 (RL2 or RR2):
Circular rotation of the register in the indicated direction.
