5.3.7 WAND (FNC 26)
Operation:
The bit patterns of the two source devices are
anal
y
zed (the contents of S

is compared a
g
ainst
the contents of S
1
). The result of the lo
g
ical AND
anal
y
sis is stored in the destination device (D).
The followin
g
rules are used to determine the result of a lo
g
ical AND operation. This takes
place for ever
