RL [%ir]		Rotate left location [ir reg.] with carry	2 cycles

Function: C 3 2 1 0 [ir]

Rotates the content of the data memory addressed by the ir register (X or Y) including the carry

(C)to the left for 1 bit. The content of the C flag moves to bit 0 of the data memory and bit 3 moves to the C flag.

	RL	[%Y]				Rotates the content of [FFimm8] (FFimm8 = FF00H + 00H to FFH)

RL [%ir]+										Rotate left location [ir reg.] with carry and increment ir reg.	2 cycles
Function:										[ir] , ir ← ir +1
		C
				3	2	1	0

Rotates the content of the data memory addressed by the ir register (X or Y) including the carry

(C)to the left for 1 bit. The content of the C flag moves to bit 0 of the data memory and bit 3 moves to the C flag. Then increments the ir register (X or Y). The increment result of the ir register does not affect the flags.
