4.3.1.2. Kit Data
Token:
0xD2
The EDBG has 256 bytes for storing kit-specific data such as MAC address, calibration values, etc. See
the kit documentation for details on how the data is organized. The information can be retrieved by using
the
Kit Data
token. Note that not all kits have kit-specific data, and the entire section will read as 0.
After sending the token, the stored kit-specific data will be sent byte-by-byte, starting with location 0, until
a stop condition is detected.
4.4.
GPIO Interface
Up to four General Purpose Input/Output (GPIO) signals are connected to DGI. In input mode, they can
be used as a status indication from the target device. In output mode, they can be used as virtual control
signals to simulate buttons.
The GPIO interface is always timestamped. It is only useful for signals with a relatively slow toggle rate
(<250kHz).
4.5.
Timestamp Module
Data received on DGI Interfaces can be routed through the timestamp module to embed timing
references into the data stream. The timestamp is implemented as a counter, which increments in steps
of (32/60) µs, giving a timestamp accuracy of about half a microsecond.
The timestamp module does not use DMA since it requires CPU intervention on each data unit received.
This implies a lower maximum data throughput and demands a larger delay between each data unit.
