6.5 Arithmetic and Logic Unit (ALU)
This unit is used to perform arithmetic and logical operations such as addition,
comparison, and bit manipulation.
6.6 Carry Flag (CY)
The carry flag contains the carry generated by the arithmetic and logical unit immediately
after an operation. The set carry (SETB CY) and clear carry (CLRB CY) instructions allow
direct access for setting and clearing this flag.
6.7 Skip Flag (SF)
The skip flag is a 1-bit register, which enables programs to conditionally skip an instruction.
All instructions are executed when this flag is
NOP instruction and resets SF to “0”. Then program execution proceeds.
The following instructions affect the skip flag
, the program executes

If carry occurs
(L) = 0
Compare
IF0 @HL.b
IF0 CY

M[HL].b = 0
(CY) = 0
(A) = M[HL].b
(A) = n

(L) = 0
The instructions, which doesn t affect the skip flag but have a skip condition, are as follows.

If it is continuous, skip next same
instruction.
If it is continuous, skip next same
instruction.
If SETB H or CLRB H are continuous,
