GNR [topic_id token_id]

Synchronous
Description:
Gets the token for the next word recognized. This command should be issued by
the host controller after it is interrupted by ISD-SR3000, following ISD-SR3000’s
recognition of a word (as evidenced by the EV_RECO_QUEUE bit being set in
the Status Word - see the GSW command). If the GNR command is issued when
the EV_RECO_QUEUE bit is not set, the GNR command will execute but the
data returned will not be valid.
Parameters:
The GNR command returns 2 bytes, defined as follows:
