Typedef Documentation

◆ GPIO_PAD

typedef uint32_t GPIO_PAD

Definition at line 281 of file gpio_dnv.h.

Enumeration Type Documentation

◆ GPIO_DIRECTION

enum GPIO_DIRECTION

GPIO Direction.

Enumerator
GpioDirDefault	Leave pad direction setting unmodified.
GpioDirInOut	Set pad for both output and input.
GpioDirInInvOut	Set pad for both output and input with inversion.
GpioDirIn	Set pad for input only.
GpioDirInInv	Set pad for input with inversion.
GpioDirOut	Set pad for output only.
GpioDirNone	Disable both output and input.

Definition at line 163 of file gpio_dnv.h.

◆ GPIO_ELECTRICAL_CONFIG

enum GPIO_ELECTRICAL_CONFIG

GPIO Electrical Configuration Set GPIO termination and Pad Tolerance (applicable only for some pads) Field from GpioTermDefault to GpioTermNative can be OR'ed with GpioTolerance1v8.

Enumerator
GpioTermDefault	Leave termination setting unmodified.
GpioTermNone	none
GpioTermWpd5K	5kOhm weak pull-down
GpioTermWpd20K	20kOhm weak pull-down
GpioTermWpu1K	1kOhm weak pull-up
GpioTermWpu2K	2kOhm weak pull-up

GpioTermNative	Native function controls pads termination.
GpioNoTolerance1v8	Disable 1.8V pad tolerance.
GpioTolerance1v8	Enable 1.8V pad tolerance.

Definition at line 230 of file gpio_dnv.h.

◆ GPIO_HARDWARE_DEFAULT

enum GPIO_HARDWARE_DEFAULT

Enumerator
GpioHardwareDefault

Definition at line 138 of file gpio_dnv.h.

◆ GPIO_HOSTSW_OWN

enum GPIO_HOSTSW_OWN

Host Software Pad Ownership modes.

Enumerator
GpioHostOwnDefault	Leave ownership value unmodified.
GpioHostOwnAcpi	Set HOST ownership to ACPI.
GpioHostOwnGpio	Set HOST ownership to GPIO.

Definition at line 154 of file gpio_dnv.h.

◆ GPIO_INT_CONFIG

enum GPIO_INT_CONFIG

GPIO interrupt configuration This setting is applicable only if GPIO is in input mode.

GPIO_INT_CONFIG allows to choose which interrupt is generated (IOxAPIC/SCI/SMI/NMI) and how it is triggered (edge or level). Field from GpioIntNmi to GpioIntApic can be OR'ed with GpioIntLevel to GpioIntBothEdgecan to describe an interrupt e.g. GpioIntApic | GpioIntLevel If GPIO is set to cause an SCI then also Gpe is enabled for this pad. Not all GPIO are capable of generating an SMI or NMI interrupt

Enumerator
GpioIntDefault	Leave value of interrupt routing unmodified.
GpioIntDis	Disable IOxAPIC/SCI/SMI/NMI interrupt generation.
GpioIntNmi	Enable NMI interrupt only.
GpioIntSmi	Enable SMI interrupt only.
GpioIntSci	Enable SCI interrupt only.
GpioIntApic	Enable IOxAPIC interrupt only.
GpioIntLevel	Set interrupt as level triggered.
GpioIntEdge	Set interrupt as edge triggered (type of edge depends on input inversion)
GpioIntLvlEdgDis	Disable interrupt trigger.
GpioIntBothEdge	Set interrupt as both edge triggered.

Definition at line 197 of file gpio_dnv.h.

◆ GPIO_LOCK_CONFIG

enum GPIO_LOCK_CONFIG

GPIO LockConfiguration Set GPIO configuration lock and output state lock GpioLockPadConfig and GpioLockOutputState can be OR'ed.

Enumerator
GpioLockDefault	Leave lock setting unmodified.
GpioPadConfigLock	Lock Pad Configuration.
GpioOutputStateLock	Lock GPIO pad output value.

Definition at line 250 of file gpio_dnv.h.

◆ GPIO_OTHER_CONFIG

enum GPIO_OTHER_CONFIG

Other GPIO Configuration GPIO_OTHER_CONFIG is used for less often settings and for future extensions Supported settings:

RX raw override to '1' - allows to override input value to '1' This setting is applicable only if in input mode (both in GPIO and native usage). The override takes place at the internal pad state directly from buffer and before the RXINV.

Enumerator
GpioRxRaw1Default	Use default input override value.
GpioRxRaw1Dis	Don't override input.
GpioRxRaw1En	Override input to '1'.

Definition at line 266 of file gpio_dnv.h.

enum GPIO_OUTPUT_STATE

GPIO Output State.

Enumerator
GpioOutDefault	Leave output value unmodified.
GpioOutLow	Set output to low.
GpioOutHigh	Set output to high.

Enumerator
GpioPadModeGpio
GpioPadModeNative1
GpioPadModeNative2
