Programmer Interface: Data

The Device Emulation Module only generates one type of event packet: DEM-UART Data Packet

DEM-UART Data Packet

A DEM-UART Data packet contains one 8-bit character, that has been sent to a UART interface by a CPU, as the only payload. All packets of this type are sent to the DI Address MOD_EVENT_DEST.

The following fields in the header of the DI packet are set:

  • FLAGS.TYPE is set to EVENT
  • FLAGS.TYPE_SUB is set to 0x00

The resulting Debug Interconnect packet has the following structure.
