g. Apply the waveforms of figure 4 to read the MDU. Wait 17 µs. Verify that it
matches the data in table XXI for the status register.
h. Select the MDU X register using the method of 4.2.3.7.3 and apply the waveforms
of figure 4, once for the high byte and once for the low byte. Verify that the logic
levels match those given in table XXI for the X register.
i. Select the MDU Y register using the method of 4.2.3.7.3 and apply the waveforms
of figure 4, once for the high byte and once for the low byte. Verify that the logic
levels match those given in table XXI for the Y register.
j. Select the MDU Z register using the method of 4.2.3.7.3 and apply the waveforms
of figure 4, once for the high byte and once for the low byte. Verify that the logic
levels match those given in table XXI for the Z register.

4.2.3.7.7 Divide with overflow indication. To determine conformance to 3.3.7.7:
a. Repeat the process of 4.2.3.7.3 substituting the data in table XXII.
b. Select the MDU status register using the method of 4.2.3.7.3. Apply figure 4 to
read the MDU and verify that it matches the data in table XXII for the status
register.
