PIC16C6X
RLF Rotate Left f through Carry
Syntax: [
label ] RLF f,d
Operands: 0  f  127
d  [0,1]
Operation: See description below
Status Affected: C
Encoding:
00 1101 dfff 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 register 'f'.
