(f
None
The contents of source register 'f
are moved to destination register
'f
anywhere in the 4096 byte data
space (000h to FFFh), and location
of destination 'f
where from 000h to FFFh.
Either source or destination can be
W (a useful special situation).
MOVFF is particularly useful for
transferring a data memory location
to a peripheral register (such as the
transmit buffer or an I/O port).
The MOVFF instruction cannot use
the PCL, TOSU, TOSH or TOSL as
the destination register.
