- Open a file and start the SD interface
- SDstart (sfstart)
- Create or open an SDS array
- SDcreate (sfcreate) - create an SDS array
SDselect (sfselect) - select an SDS array
- Perform optional operations (reading writing, etc ..)
- Terminate access to the data array
- SDendaccess (sfendacc)
- Terminate access to the SD interface and close the file
- SDend (sfend)
