41 //#####DESCRIPTIONBEGIN####
46 // Description: Simple driver for the SH Serial Communication Interface
47 // The driver can be used for either the SCIF or the IRDA
48 // modules (the latter can act as the former).
49 // Clients of this file can configure the behavior with:
50 // CYGNUM_SCIF_PORTS: number of SCI ports
52 // Note: It should be possible to configure a channel to IRDA mode.
53 // Worry about that when some board needs it.
