Here is the EEPROM Read code found on
Page 93 of the 16f628 data sheet.

BCF STATUS, RP0 ; Bank 0
MOVLW CONFIG_ADDR ;
MOVWF EEADR ; Address to read
BSF STATUS, RP0 ; Bank 1
BSF EECON1, RD ; EE Read
BCF STATUS, RP0 ; Bank 0
MOVF EEDATA, W ; W = EEDATA

Everything seems fine except for the last line.
The register map shows that EEDATA is in Bank1.
So reading EEDATA would actually read RCREG!

Is this an error in the data sheet ?
I guess they merely copied the routine from
The 16f84 data sheet. How misguiding this could
be to newbies!
