MOVSS [z

((FSR2) + z
None
The contents of the source register are
moved to the destination register. The
addresses of the source and destination
registers are determined by adding the
7-bit literal offsets, ‘z
respectively, to the value of FSR2. Both
registers can be located anywhere in
the 4096-byte data memory space
(000h to FFFh).
The MOVSS instruction cannot use the
PCL, TOSU, TOSH or TOSL as the
destination register.
If the resultant source address points to
an Indirect Addressing register, the
value returned will be 00h. If the
resultant destination address points to
an Indirect Addressing register, the
instruction will execute as a NOP .

The 8-bit literal ‘k’ is written to the data
memory address specified by FSR2.
FSR2 is decremented by 1 after the
operation.
This instruction allows users to push
values onto a software stack.
