11.6 Write Verify

Depending on the application, good programming

practice may dictate that the value written to the data

EEPROM or program memory should be verified (see

Example 11-6) to the desired value to be written.

Example 11-6 shows how to verify a write to EEPROM.

EXAMPLE 11-6: EEPROM WRITE VERIFY

BANKSEL EEDATL

;

MOVF EEDATL, W ;EEDATL not changed

;from previous write

BSF

EECON1, RD ;YES, Read the

;value written

XORWF EEDATL, W ;

BTFSS STATUS, Z ;Is data the same

GOTO WRITE_ERR ;No, handle error

:

;Yes, continue
