U10B (74HC73) is used as a handshake flip-flop
with the computer system attached to the evalu-
ation board. The board brings DRDY low. The
computer reads the data and then sets DACK mo-
mentarily high. This resets U10B for the next
word. This handshake can be disabled by setting
P8 jumper to position 1.
