pic12f629 EEPROM problem in MPLABSIM

[mister_e]

MPSIM can be a real pain in few occasion, what i suggest is to loop on the READ subroutine and wait the Watch Windows to refresh.

        include     P12F629.inc
        errorlevel -302
        __CONFIG    _INTRC_OSC_NOCLKOUT & _MCLRE_ON & _WDT_OFF & _PWRTE_ON & _BODEN_ON 
        
MyData = 0xFA ; whatever your value
MyAddr = 0x10 ; EEPROM Address    
TEMP            EQU 0x21

        org     0
        call    WRITE
        call    READ
        goto    $-1



WRITE: 
        BANKSEL EECON1
        MOVLW   MyAddr
        MOVWF   EEADR
        MOVLW   MyData
        MOVWF   EEDATA
        BSF     EECON1,WREN
        MOVLW   0X55
        MOVWF   EECON2
        MOVLW   0XAA
        MOVWF   EECON2
        BSF     EECON1,WR
        BCF     EECON1,WREN
        RETURN

READ: 
        BANKSEL EEADR
        MOVLW   MyAddr
        MOVWF   EEADR;
        BSF     EECON1,RD 
        MOVF    EEDATA,W 
        BANKSEL TEMP
        MOVWF   TEMP  
        RETURN
        
        end

NOTE: This may not work in 'Animate' mode.
