RETURN
Return from Subroutine
Syntax:
RETURN {s}
Operands:
s

STATUS,
(BSRS)
BSR,
PCLATU, PCLATH are unchanged
Status Affected:
None
Encoding:

0001
001s
Description:
Return from subroutine. The stack is
popped and the top of the stack (TOS)
is loaded into the program counter. If
‘s’= 1, the contents of the shadow
registers WS, STATUSS and BSRS are
loaded into their corresponding
registers W, STATUS and BSR. If
‘s’ = 0, no update of these registers
occurs (default).

Description:
The contents of register ‘f’ are rotated
one bit to the left through the Carry flag.
If ‘d’ is ‘0’, the result is placed in W. If ‘d’
is ‘1’, the result is stored back in register
‘f’ (default).
If ‘a(chǎn)’ is ‘0’, the Access Bank is selected.
If ‘a(chǎn)’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a(chǎn)’ is ‘0’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f
95 (5Fh). See
