7 APPLICATION INSTRUCTIONS
7.1 Rotation Instructions
Rotating 16-bit binary data to the left
ROL(P), RCL(P)
• ROL(P): These instructions rotate the 16-bit binary data to the left by (n) bit(s), excluding the carry flag.
• RCL(P): These instructions rotate the 16-bit binary data to the left by (n) bit(s), including the carry flag.
*1 The ROL instruction does not support the ST and FBD/LD. Use the standard function, ROL.
