_GotoSleep:
; fill remainder of the last row with NOP instructions
; Place SLEEP instruction in the last word of program memory
Execution of the Sleep instruction (PWRSAV #0)
may cause incorrect program operation after the
device wakes up from Sleep. The current
consumption during Sleep may also increase
beyond the specifications listed in the device data
sheet.
Work arounds
To avoid this issue, implement any of the following
three work arounds, depending on the application
requirements.
Work around 1:
Ensure that the PWRSAV #0 instruction is located
at the end of the last row of program Flash memory
available on the target device and fill the
remainder of the row with NOP instructions.

; Set up INT pins to detect falling edge
; Clear interrupt pin interrupt flag bits
; Enable ISR processing for INT pins
; Call function to enter SLEEP mode

; Ensure flag is reset
; Return from Interrupt Service Routine
This can be accomplished by replacing all
occurrences of the PWRSAV #0 instruction with a
function call to a suitably aligned subroutine. The
address( ) attribute provided by the MPLAB
ASM30 assembler can be utilized to correctly align
the instructions in the subroutine. For an
application written in C, the function call would be
GotoSleep( ), while for an assembly language
application,
CALL _GotoSleep.
The Address Error Trap Service Routine (TSR)
software can then replace the invalid return
address saved on the stack with the address of the
instruction immediately following the _GotoSleep
or GotoSleep( ) function call. This ensures that
the device continues executing the correct code
sequence after waking up from Sleep mode.
