Test Mode
The TEST input is a three-level input. In normal system operation,
this pin is connected to ground, allowing the PI6C39911 to operate
as explained briefly above (for testing purposes, any of the three
level inputs can have a removable jumper to ground, or be tied LOW
through a 100 Ohm resistor. This will allow an external tester to
change the state of these pins.)
If the TEST input is forced to its MID or HIGH state, the device will
operate with its internal phase locked loop disconnected, and input
levels supplied to REF will directly control all outputs. Relative
output to output functions are the same as in normal mode.
In contrast with normal operation (TEST tied LOW). All outputs
will function based only on the connection of their own function
select inputs (xF0 and xF1) and the waveform characteristics of the
REF input.
