| 6 | ======================= |
---|
| 7 | |
---|
| 8 | sDeviceName |
---|
| 9 | |
---|
| 10 | The name of this device. |
---|
| 11 | |
---|
| 12 | deviceType |
---|
| 13 | |
---|
| 14 | This field must be SERIAL_MG5UART. |
---|
| 15 | |
---|
| 16 | pDeviceFns |
---|
| 17 | |
---|
| 18 | The device interface control table. This may be: |
---|
| 19 | + mg5uart_fns for interrupt driven IO |
---|
| 20 | + mg5uart_fns_polled for polled IO |
---|
| 21 | |
---|
| 22 | deviceProbe |
---|
| 23 | |
---|
| 24 | This is the address of the routine which probes to see if the device |
---|
| 25 | is present. |
---|
| 26 | |
---|
| 27 | pDeviceFlow |
---|
| 28 | |
---|
| 29 | This field is ignored as hardware flow control is not currently supported. |
---|
| 30 | |
---|
| 31 | ulMargin |
---|
| 32 | |
---|
| 33 | This is currently unused. |
---|
| 34 | |
---|
| 35 | ulHysteresis |
---|
| 36 | |
---|
| 37 | This is currently unused. |
---|
| 38 | |
---|
| 39 | pDeviceParams |
---|
| 40 | |
---|
| 41 | This is set to the default settings. |
---|
| 42 | |
---|
| 43 | ulCtrlPort1 |
---|
| 44 | |
---|
| 45 | This field is the address of the command register shared by both ports. |
---|
| 46 | |
---|
| 47 | ulCtrlPort2 |
---|
| 48 | |
---|
| 49 | This field is the address of the port being used. |
---|
| 50 | |
---|
| 51 | ulDataPort |
---|
| 52 | |
---|
| 53 | This field is set to MG5UART_PORTA or MG5UART_PORTB. |
---|
| 54 | |
---|
| 55 | getRegister |
---|
| 56 | setRegister |
---|
| 57 | |
---|
| 58 | These do NOT follow standard conventions and are ignored. |
---|
| 59 | The register address routines are hard-coded as this is |
---|
| 60 | an on-CPU part and assumed to provide a 32-bit wide interface. |
---|
| 61 | |
---|
| 62 | getData |
---|
| 63 | |
---|
| 64 | This is address of the RX buffer register. |
---|
| 65 | |
---|
| 66 | setData |
---|
| 67 | |
---|
| 68 | This is address of the TX buffer register. |
---|
| 69 | |
---|
| 70 | ulClock |
---|
| 71 | |
---|
| 72 | baudRate Clock |
---|
| 73 | |
---|
| 74 | ulIntVector |
---|
| 75 | |
---|
| 76 | This is the interrupt vector number associated with this chip. |
---|
| 77 | |
---|
| 78 | Example: |
---|
| 79 | |
---|
| 80 | #if (CONSOLE_USE_INTERRUPTS) |
---|
| 81 | #define MG5UART_FUNCTIONS &mg5uart_fns |
---|
| 82 | #else |
---|
| 83 | #define MG5UART_FUNCTIONS &mg5uart_fns_polled |
---|
| 84 | #endif |
