This mode offers the following advantages:

•Only one measurement is taken at a time.

•The trigger is edge-sensitive, so it can be retriggered in each X2X Link cycle.

•The toggle bit toggles with every new value.

The following must be taken into consideration for the configuration:

•A new trigger will be ignored during an ongoing measurement. The runtime on the bus can cause retriggering before the toggle bit has changed.

•If a shorter sample time than the X2X Link cycle time is configured, the last complete measurement is always transferred.

•In trigger mode, values are lost because the measured values are recorded acyclically to the X2X Link and cannot be synchronized continually.

•The trigger results in temporary synchronization with X2X Link.

 

此模式具有以下优点：

•一次只进行一个测量。

•触发器是沿触发，因此可以在每个X2X链路周期中重新触发。

•切换位随每个新值进行切换。

配置时必须考虑以下因素：

•在正在进行的测量过程中，新的触发器将被忽略。总线上的运行时可能会导致在切换位更改之前重新触发。

•如果配置的采样时间比 X2X Link 周期时间短，则始终传输最后一个完整的测量值。

•在触发模式下，由于测量值非循环地记录到 X2X 链路中，并且无法连续同步，因此值会丢失。

•触发器会导致与X2X链路的临时同步。
