There are numerous mistakes in many of the Microchip datasheets - I've found
a few on the eeprom examples in some of the 16F datasheets

Subject: [PIC] Am I crazy or is this datasheet?

Whoops forgot to tag it the first time...

Here is the sample code given in Microchip's datasheet for the
PIC18F4525 (DS3926B) Page 105 the pdf can be found here:
http://ww1.microchip.com/downloads/en/DeviceDoc/39626b.pdf
 
 CLRF PORTA ; Initialize PORTA by
 ; clearing output
 ; data latches
 CLRF LATA ; Alternate method
 ; to clear output
 ; data latches
 MOVLW 07h ; Configure A/D
 MOVWF ADCON1 ; for digital inputs
 MOVWF 07h ; Configure comparators
 MOVWF CMCON ; for digital input
 MOVLW 0CFh ; Value used to
 ; initialize data
 ; direction
 MOVWF TRISA ; Set RA<7:6,3:0> as inputs  ; RA<5:4> as outputs
 
 I see two problems... MOVWF 07h should be a MOVLW 07h as far as I can tell,
and shouldn't we actually put 0fh into ADCON1?
 
 I'm not crazy, right? I see nothing about this in the errata
