d
See description below
C
The contents of register ‘f’ are
rotated one bit to the right
through the Carry flag. If ‘d’ is ‘0’,
the result is placed in the W
register. If ‘d’ is ‘1’, the result is
placed back in register ‘f’.
Rotate Left f through Carry
[ label ]
0
d
See description below
C
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’.
