Context Saving During Interrupts
During an interrupt, only the return PC value is saved
on the stack. Typically, users may wish to save key
registers during an interrupt (e.g., W and STATUS
registers). This must be implemented in software.
Since the lower 16 bytes of all banks are common in the
PIC12F683 (see Figure 3-2), temporary holding regis-
ters, W_TEMP and STATUS_TEMP, should be placed
in here. These 16 locations do not require banking and
therefore, makes it easier to context save and restore.
The same code shown in Example 12-1 can be used
to:
Store the W register.
Store the STATUS register.
Execute the ISR code.
Restore the Status (and Bank Select Bit register).
Restore the W register.
EXAMPLE 12-1:
SAVING STATUS AND W REGISTERS IN RAM
Note:
The PIC12F683 normally does not require
saving the PCLATH. However, if com-
puted GOTO’s are used in the ISR and the
main code, the PCLATH must be saved
and restored in the ISR.
MOVWF
W_TEMP
;Copy W to TEMP register
SWAPF
STATUS,W
;Swap status to be saved into W
;Swaps are used because they do not affect the status bits
MOVWF
STATUS_TEMP
;Save status to bank zero STATUS_TEMP register
:
:(ISR)
;Insert user code here
:
SWAPF
STATUS_TEMP,W
;Swap STATUS_TEMP register into W
;(sets bank to original state)
MOVWF
STATUS
;Move W into STATUS register
SWAPF
W_TEMP,F
;Swap W_TEMP
SWAPF
W_TEMP,W
;Swap W_TEMP into W
