Context Saving During Interrupts
During an interrupt, only the return PC value is saved
on the stack. Typically, users may wish to save key reg-
isters during an interrupt, i.e., W register and STATUS
register. This will have to be implemented in software.
Example 10-1 stores and restores the W and STATUS
registers. The register, W_TEMP, must be dened in
each bank and must be dened at the same offset from
the bank base address (i.e., if W_TEMP is dened at
0x20 in bank 0, it must also be dened at 0xA0 in bank
1).
The example:
a)
Stores the W register.
b)
Stores the STATUS register in bank 0.
c)
Executes the ISR code.
d)
Restores the STATUS register (and bank select
bit).
e)
Restores the W register.
EXAMPLE 10-1: SAVING STATUS, W, AND PCLATH REGISTERS IN RAM
MOVWF
W_TEMP
;Copy W to W_TEMP register, could be bank one or zero
SWAPF
STATUS,W
;Swap status to be saved into W
CLRF
STATUS
;bank 0, regardless of current bank, Clears IRP,RP1,RP0
MOVWF
STATUS_TEMP
;Save status to bank zero STATUS_TEMP register
:
Interrupt Service Routine (ISR) - user defined
:
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
