PARALLEL OUTPUT (After a Conversion)
After conversion
N
is completed and the output registers have been updated, BUSY (pin 24) goes high. Valid
data from conversion
N
is available on D7-D0 (pin 9-13 and 15-17). BUSY going high can be used to latch the
data. Refer to
Table 5
and
Figure 33
and
Figure 34
for timing specifications.
