Test Mode
The TEST input is a three-level input. In normal system oper-
ation, this pin is connected to ground, allowing the CY7B991V
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 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.
