Not entirely correct. Pass a pointer, check error
if (prussdrv_map_extmem(&sequenceData))
{ /* error handling here */ }
sequenceData[0] = 0815;

Note: the ERam has a default size of 256 kB. In order to get 1 MB, you'll
have to load the driver manually (8 MB max.). See this documentation
<http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_memory.html>
(section ERam at the bottom) for details.
