// 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
|
| 51 |
|
|
//
|
| 52 |
|
|
// Note: It should be possible to configure a channel to IRDA mode.
|
| 53 |
|
|
// Worry about that when some board needs it.
