#11827 - RE: an efficient parity generation scheme ?
Tommy look for these examples:

; Contrôle de la parité d'un octet reçu.
PUSH ACC
CLR ACC.7 ; ;Efface le bit de poids fort (parité)
ADD A,#0 ; ;Calcul de la parité théorique
MOV C,PSW.0
CPL C ; ;Parité impaire
MOV ACC.7,C
POP B
CJNE A,B,PRCDHS ; ;Comparaison réception et calcul
LJMP PRCDOK
PRCDHS SETB B_ERR_RCD ; ;Parité érronée.
PRCDOK CLR ACC.7
:::::::::::::::::::::::::::::::::::
; Génération de la parité
CLR ACC.7
ADD A,#00H
MOV C,PSW.0
CPL C
;Parité Impaire
MOV ACC.7,C
MOV SBUF,A
RET

Have fun sorry for french comments
Vincent
