Management commands for optional Test Inputs.

-

CMSIS-DAP provides a command set that allows to implement an optional Test Input (TI) management in the Debug Unit. Recording of up to 16 different Test Inputs is possible. Test Input values can be recorded as BYTE, SHORT, or WORD. The Debug Unit may include scaling parameters and dynamic ranges for a channel (for example a 14-bit value with a 2-bit range selection).

-

Test Inputs could be used for various scenarios, for example:

-

capture power measurement from A/D converters.
capture wait states or cache misses from a memory system.
capture data transfer parameters of an RF interface.
test input pins of a Debug Unit.

-

These Test Inputs can be recorded continuously with a specified trace recording frequency. The recording allows you to correlate the Test Input information with program execution. For recording of the CMSIS-DAP Firmware includes an optional Trace Data Management based on configurable memory blocks. This Trace Data Management also captures SWO trace information.

-

Note: The Test Input Commands are only available when DAP_Info with ID=0xF0 (Capabilities) returns in Info - Bit 6: 1 = Trace Data Management.
