ROTXL (ROTate with eXtend carry Left)
Operation
Rd (left rotation through carry flag)
Assembly-Language Format
ROTXL.W Rd
Operand Size
Word
Description
This instruction rotates the bits in a 16-bit register Rd (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 15) rotates into the carry flag.
Available Registers
Rd: R0 to R7, E0 to E7
