Function Documentation

◆ dt_pinmux_alert_from_alert_id()

dt_pinmux_alert_t dt_pinmux_alert_from_alert_id	(	dt_pinmux_t	dt,
		dt_alert_id_t	alert )

Convert a global alert ID to a local pinmux alert type.

Parameters

dt	Instance of pinmux.
alert	A global alert ID that belongs to this instance.

Returns: The pinmux alert, or kDtPinmuxAlertCount.

Note: This function assumes that the global alert ID belongs to the instance of pinmux passed in parameter. In other words, it must be the case that dt_pinmux_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtPinmuxAlertCount.

Definition at line 107 of file dt_pinmux.c.

◆ dt_pinmux_alert_to_alert_id()

dt_alert_id_t dt_pinmux_alert_to_alert_id	(	dt_pinmux_t	dt,
		dt_pinmux_alert_t	alert )

Get the alert ID of a pinmux alert for a given instance.

Note: This function only makes sense if the instance is connected to the Alert Handler. For any instances where the instance is not connected, the return value is unspecified.

Parameters

dt	Instance of pinmux.
alert	A pinmux alert.

Returns: The Alert Handler alert ID of the alert of this instance.

Definition at line 101 of file dt_pinmux.c.

◆ dt_pinmux_clock()

dt_clock_t dt_pinmux_clock	(	dt_pinmux_t	dt,
		dt_pinmux_clock_t	clk )

Get the clock signal connected to a clock port of an instance.

Parameters

dt	Instance of pinmux.
clk	Clock port.

Returns: Clock signal.

Definition at line 119 of file dt_pinmux.c.

◆ dt_pinmux_from_instance_id()

dt_pinmux_t dt_pinmux_from_instance_id ( dt_instance_id_t inst_id )

Get the pinmux instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id Instance ID.

Returns: A pinmux instance.

Note: This function only makes sense if the instance ID has device type pinmux, otherwise the returned value is unspecified.

Definition at line 67 of file dt_pinmux.c.

◆ dt_pinmux_instance_id()

dt_instance_id_t dt_pinmux_instance_id ( dt_pinmux_t dt )

Get the instance ID of an instance.

Parameters

dt	Instance of pinmux.

Returns: The instance ID of that instance.

Definition at line 74 of file dt_pinmux.c.

◆ dt_pinmux_memory_base()

uint32_t dt_pinmux_memory_base	(	dt_pinmux_t	dt,
		dt_pinmux_memory_t	mem )

Get the base address of a memory.

Parameters

dt	Instance of pinmux.
mem	The memory requested.

Returns: The base address of the requested memory.

Definition at line 86 of file dt_pinmux.c.

◆ dt_pinmux_memory_size()

uint32_t dt_pinmux_memory_size	(	dt_pinmux_t	dt,
		dt_pinmux_memory_t	mem )

Get the size of a memory.

Parameters

dt	Instance of pinmux.
mem	The memory requested.

Returns: The size of the requested memory.

Definition at line 93 of file dt_pinmux.c.

◆ dt_pinmux_reg_block()

uint32_t dt_pinmux_reg_block	(	dt_pinmux_t	dt,
		dt_pinmux_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of pinmux.
reg_block	The register block requested.

Returns: The register base address of the requested block.

Definition at line 79 of file dt_pinmux.c.

◆ dt_pinmux_reset()

dt_reset_t dt_pinmux_reset	(	dt_pinmux_t	dt,
		dt_pinmux_reset_t	rst )

Get the reset signal connected to a reset port of an instance.

Parameters

dt	Instance of pinmux.
rst	Reset port.

Returns: Reset signal.
