Nucleus Number 2200
Description Resets the DTTM module in diagnostic mode, and the communication to it.
Note This reset action is also done before the first of the other executed DTTM
nuclei, to set-up communications with the DTT module.
Technical - Setup of the Basic Engine UART port, which connects to the DTT Module.
- Make RTS pin of the UART inactive
- Toggle the reset-pin of the DTT Module
- Wait for DTTM to become online
- Send the Boot loader start character to the DTT Module
- Check if the DTT Module boot loader accepted the character.
It must return "READY>"
- Put the DTTM into D&S command mode.
- Empty the DTTM output buffer
- Set Reset flag to prevent resetting before every nucleus.
Execution Time Approx. 5 sec.
User Input None
Error Number Description
220000 The DTT Module has been successfully reset.
