The open condition is selected at power ON/reset.
* IF counter counting end check
With end-UC set and IF counter starting (CTE = 0
→1), DO pin opens automatically.
At end of counting of the IF counter, DO pin goes LOW and check on counting end can be made.
DO pin opens when serial data is entered/output (CE pin : Hi)
Note : DO pin is always in the open condition during data input (IN1 and IN2 modes, during CE : Hi
period), regardless of DO pin control data (DOC0 to 2). In the DO pin condition during data output
(OUT mode, CE-Hi period), the content of internal DO serial data is output in synchronization with
CL, regardless of DO pin control data (DOC).

Forced to LOW
In case of dead lock because of VCO oscillation stop when the VCO control voltage (Vtune) is 0V,
it is possible to clear dead lock by setting the charge pump output to LOW and V tune to VCC.
