(PCLATU) → PCU
None
First, the return address (PC + 2) is
pushed onto the return stack. Next, the
contents of W are written to PCL; the
existing value is discarded. Then, the
contents of PCLATH and PCLATU are
latched into PCH and PCU,
respectively. The second cycle is
executed as a
new next instruction is fetched.

The contents of the source register are
moved to destination register ‘f
actual address of the source register is
determined by adding the 7-bit literal
offset ‘z
FSR2. The address of the destination
register is specified by the 12-bit literal
‘f
can be anywhere in the 4096-byte data
space (000h to FFFh).
The MOVSF 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.
