The TR allows for two different triggers to be set to allow for the data transfer to be prevented or halted through the process of transferring the data. The triggers are specified by selecting a type of trigger and the size of the transfer that can be allowed for the receipt of a given trigger. The triggers themselves in the UTC are collected on a per channel basis and for each of three sources. Anytime the trigger event is received the internal counter is incremented. The trigger event will not be cleared until the specified block has started its transfer and it will only clear the triggers that are active.
This does allow for one TR in the channel to use global event 0 and the next TR to use global event 1. If while the first TR is running global event 0 can increment and will decrement each time the TR reaches the specified level. At the same time global event 1 will be incremented whenever it is received but it will not decrement until the next TR runs. If the global event 1 counter reaches overflows then an error event will NOT be generated but the event will be lost.
