Information in Detail
The XE166 family supports variety of start-up modes, allowing the user to make selections in three aspects:
•
Main functionality - where from the user code will be started (on-chip Flash, PSRAM, external memory);
•
Optionally - a way for initial code-downloading into PSRAM before to start it:
– From an external host via a communication interface - UART, CAN, SSC;
– From Stand-by RAM (SBRAM) - after exiting a power-saving mode;
•
Debug-related - either debugging will be possible, and if Yes - which debug-interface to use (JTAG, DAP,
selectable pin-assignments).
The Easy Kit Board Manual covers only a limit numbers of start-up modes. For all possible start-up modes please
refer to the corresponding user manual.
