Clock x Disable State.
Where x = 4, 5, 6, 7. These 2 bits determine the state of the CLKx output when dis-
abled. Individual output clocks can be disabled using register Output Enable Con-
trol located at address 3. Outputs are also disabled using the OEB pin.
00: CLKx is set to a LOW state when disabled.
01: CLKx is set to a HIGH state when disabled.
10: CLKx is set to a HIGH IMPEDANCE state when disabled.
11: CLKx is NEVER DISABLED.
