Note
The signals marked with asterisk symbol (*) are not supported on the conga-QA5.
On Apollo Lake SoC, the signals marked with asterisks (**) have voltage levels that are different from the levels defined in the Qseven
Specification. To comply with the Qseven Specification, the signals are routed through bidirectional level shifters on the module.
The bidirectional level shifters by nature have limited driving strength. congatec therefore recommends to route these signals as short as
possible.
External pull up/down resistors <100k ohm are not allowed on these signals.
