Rotate and Shift
A major feature of the Z80 is to rotate or shift data in the accumulator, any
general-purpose register, or any memory location. All the rotate and shift
Op Codes are depicted in Figure 14. Also included in the Z80 are
arithmetic and logical shift operations. These operations are useful in a
wide range of applications including integer multiplication and division.
Two BCD digit rotate instructions (
accumulator to be rotated with the two digits in a memory location
pointed to by register pair HL (See Figure 14). These instructions allow
for efficient BCD arithmetic.
