35.5.1.1 Single, Dual or Quad Lane Modes

The lane modes (single/dual/quad), as the names imply set the interface to exercise transactions using single (SQID0), dual (SQID0, SQID1) or quad (SQID0-SQID3) data lanes. The majority of serial Flash devices provide commands specifically to exercise the transactions in a specific lane mode (i.e., JEDEC-ID to read device ID in single lane mode and QJID to read the same device ID in quad lane mode in case of SST26VF series devices).
