RLF Rotate Left f through Carry
Syntax: [
label ] RLF f,d
Operands: 0  f  31
d  [0,1]
Operation: See description below
Status Affected: C
Encoding:
0011 01df ffff
Description: The contents of register 'f' are
rotated one bit to the left through
the Carry Flag. If 'd' is 0, the result
is placed in the W register. If 'd' is
1, the result is stored back in regis-
ter 'f'.
