7
Rotating 32-bit binary data to the left
DROL(P), DRCL(P)
• DROL(P): These instructions rotate the 32-bit binary data to the left by (n) bit(s), excluding the carry flag.
• DRCL(P): These instructions rotate the 32-bit binary data to the left by (n) bit(s), including the carry flag.
*1 The DROL instruction does not support the ST and FBD/LD. Use the standard function, ROL.
