Operation
Rd (left arithmetic shift)
Assembly-Language Format
SHAL.B #2, Rd
Operand Size
Byte
Description
This instruction shifts the bits in an 8-bit register Rd (destination operand) two bits to the left. Bit
6 shifts into the carry flag. Bits 0 and 1 are cleared to 0.
Available Registers
Rd: R0L to R7L, R0H to R7H
Operand Format and Number of States Required for Execution
Notes
The SHAL instruction differs from the SHLL instruction in its effect on the overflow flag.
