ROTXL (ROTate with eXtend carry Left)
Operation
ERd (left rotation through carry flag)
Assembly-Language Format
ROTXL.L ERd
Operand Size
Longword
Description
This instruction rotates the bits in a 32-bit register ERd (destination operand) one bit to the left
through the carry flag. The carry flag is rotated into the least significant bit (bit 0). The most
significant bit (bit 31) rotates into the carry flag.
Available Registers
