Executing the time stamp function for the 1st entry
In order that the outputs can be triggered accordingly, you have to enable them before. In this
example, you enable both outputs with the 1st "running number" (RN).
The 1st time stamp entry (RN = 0x01) is executed and deleted from the FIFO memory.
The diagram indicates the status of the outputs at the "t" time.

Executing the time stamp function for the entries 2 ... 4
The states of the time stamp entries 2 ... 4 (RN = 0x02 ... 0x04) are output successively and deleted
from the FIFO memory.
The diagram indicates the status of the outputs at the "t" time.
