Input and output triggers
There are two trigger pins on the ST7-DVP3 development board, TRIGOUT and
TRIGIN (see
capability will help you ensure that the ST7 microcontroller’s activities are well-
synchronized with other devices in your application. With STVD7, these triggers
allow you to:
•
•
Hardware events and the external output trigger (TRIGOUT)
The ST7-DVP3 development board features a TRIGOUT pin from which a signal
can be sent out. See
The sending of trigger signals is controlled by hardware events. There are three
types of hardware event:
•
•
•
Generate a break in the execution of your application. When combined with
trace recording, it is possible to track the sequence of events that precede and
follow the reception of an external signal.
Generate an output trigger signal to be sent upon the occurrence of a
hardware event. Hardware events are explained in detail in the STVD7 User
Manual . Trace recording can also be synchronized around a hardware event.
Event On (EVT_ON): Upon a memory read or write at a specified address, or
the occurrence of specified variable, the trigger output signal is set high. You
can also choose to have trace recording begin simultaneously.
Event Off (EVT_OFF): Upon a memory read or write at a specified address, or
the occurrence of specified variable, the trigger output signal is set low. You
can use this to end trace recording.
Event Hit (EVT_HIT): Upon a memory read or write at a specified address, or
the occurrence of specified variable, the trigger output signal is set high for the
cycles in which one particular address is accessed.
