(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
anywhere 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.
