54 | | At the time of writing, the console driver operates the UART in polling mode only. |
| 54 | The console driver can operate in polling mode or interrupt mode, which mode is used is selected at compile time using the CONSOLE_USE_INTERRUPT configuration option. All UARTs are operate in the same mode. |

| 57 | With the -u option to GRMON, GRMON will set one UART in "debug-mode" or loop-back (older hardware) mode in order to tunnel the UART output/input over the debug-link to the PC instead of at the physical UART connector of the PCB. |

| 59 | Note that it is not possible to use the interrupt mode of the driver together with the "old" APBUART and -u to GRMON. However the new |
| 60 | APBUART core (from GRLIB 1.0.17-b2710) has the GRMON debug bit and can handle interrupts. Please see the GRMON manual. |
