GEReq_endofpass()

int GEReq_endofpass

(

)

Sets SSP word in sequence off_GEpass() to trigger data (Pfile) writing and reconstruction

After calling this function, the parent function must switch back to the previous/main sequence using ks_scan_playsequence() (or boffset()).

#ifdef IPG
  boffset(off_GEpass);
  setwamp(SSPD + DABPASS, &GEendpass, 2 ); /* end of pass */
  startseq(0, (short) MAY_PAUSE);
#else
  /* HOST */
  ks_plot_slicetime(&seqctrl_passpack, 1, NULL, KS_NOTSET, KS_PLOT_STANDARD);

  KS_DESCRIPTION slicegroup_desc;
  sprintf(slicegroup_desc, "endofpass");
  ks_plot_slicetime_endofslicegroup_tagged(slicegroup_desc, KS_PLOT_SG_ACQUISITION);

  seqctrl_passpack.nseqinstances++;
