* nRF51 System-on-Chip general purpose input/output register definition
|
|
*
|
|
* QEMU interface:
|
|
* + sysbus MMIO regions 0: GPIO registers
|
|
* + Unnamed GPIO inputs 0-31: Set tri-state input level for GPIO pin.
|
|
* Level -1: Externally Disconnected/Floating; Pull-up/down will be regarded
|
|
* Level 0: Input externally driven LOW
|
|
* Level 1: Input externally driven HIGH
|
|
* + Unnamed GPIO outputs 0-31:
|
|
* Level -1: Disconnected/Floating
|
|
* Level 0: Driven LOW
|
|
* Level 1: Driven HIGH
|
|
*
|
|
* Accuracy of the peripheral model:
|
|
* + The nRF51 GPIO output driver supports two modes, standard and high-current
|
|
* mode. These different drive modes are not modeled and handled the same.
|
|
* + Pin SENSEing is not modeled/implemented.
