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.

DIP Switches

Figure 7 and Table 3 shows the DIP switch se-

lectable options.

Test Points
