Input Triggering Technology
Overview of DAP Input Triggering and Clocking
DAP sampling hardware provides three triggering modes and two sampling modes. They can be used in any combination. All triggering and sampling modes are specified in a downloaded DAPL configuration script.
When a digital signal is not available for hardware triggering, and in some situations even when such a signal is available, software triggering provides an alternative with more flexibility.
There are three triggering modes:
After sampling starts, samples are captured on each
active-high pulse of the digital sampling clock. The clocking
signal is selected by the
The two sampling modes are:
