Aeroflex Gaisler GRGPIO General Purpose I/O cores.
|
|
|
|
The GRGPIO GPIO core is available in the GRLIB VHDL IP core library.
|
|
|
|
Note: In the ordinary environment for the GRGPIO core, a Leon SPARC system,
|
|
these properties are built from information in the AMBA plug&play.
|
|
|
|
Required properties:
|
|
|
|
- name : Should be "GAISLER_GPIO" or "01_01a"
|
|
|
|
- reg : Address and length of the register set for the device
|
|
|
|
- interrupts : Interrupt numbers for this device
|
|
|
|
Optional properties:
|
|
|
|
- nbits : The number of gpio lines. If not present driver assumes 32 lines.
|
|
|
|
- irqmap : An array with an index for each gpio line. An index is either a valid
|
|
index into the interrupts property array, or 0xffffffff that indicates
|
|
no irq for that line. Driver provides no interrupt support if not
|
|
present.
