PL011 functions
function PL011UARTCreate(Address:LongWord; const Name:String; IRQ,ClockRate:LongWord):PUARTDevice;
Description: Create and register a new PL011 UART device which can be accessed using the UART API
| Address | The address of the PL011 registers |
|---|---|
| Name | The text description of this device which will show in the device list (Optional) |
| IRQ | The interrupt number for the PL011 |
| ClockRate | The clock source frequency for the PL011 |
| Return | Pointer to the new UART device or nil if the UART device could not be created |
function PL011UARTDestroy(UART:PUARTDevice):LongWord;
Description: Close, deregister and destroy a PL011 UART device created by this driver
| UART | The UART device to destroy |
|---|---|
| Return | ERROR_SUCCESS if completed or another error code on failure |
