None
The contents of source register ‘f
moved to destination register ‘f
Location of source ‘f
in the 4096-byte data space (000h to
FFFh) and location of destination ‘f
can also be 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.
