Function Documentation

◆ dt_aon_timer_alert_from_alert_id()

dt_aon_timer_alert_t dt_aon_timer_alert_from_alert_id	(	dt_aon_timer_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns: The aon_timer alert, or kDtAonTimerAlertCount.

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

Definition at line 137 of file dt_aon_timer.c.

◆ dt_aon_timer_alert_to_alert_id()

dt_alert_id_t dt_aon_timer_alert_to_alert_id	(	dt_aon_timer_t	dt,
		dt_aon_timer_alert_t	alert )

Get the alert ID of a aon_timer 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 aon_timer.
alert	A aon_timer alert.

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

Definition at line 131 of file dt_aon_timer.c.

◆ dt_aon_timer_clock()

dt_clock_t dt_aon_timer_clock	(	dt_aon_timer_t	dt,
		dt_aon_timer_clock_t	clk )

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

Parameters

dt	Instance of aon_timer.
clk	Clock port.

Returns: Clock signal.

Definition at line 149 of file dt_aon_timer.c.

◆ dt_aon_timer_from_instance_id()

dt_aon_timer_t dt_aon_timer_from_instance_id ( dt_instance_id_t inst_id )

Get the aon_timer instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id Instance ID.

Returns: A aon_timer instance.

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

Definition at line 73 of file dt_aon_timer.c.

◆ dt_aon_timer_instance_id()

dt_instance_id_t dt_aon_timer_instance_id ( dt_aon_timer_t dt )

Get the instance ID of an instance.

Parameters

dt	Instance of aon_timer.

Returns: The instance ID of that instance.

Definition at line 80 of file dt_aon_timer.c.

◆ dt_aon_timer_irq_from_plic_id()

dt_aon_timer_irq_t dt_aon_timer_irq_from_plic_id	(	dt_aon_timer_t	dt,
		dt_plic_irq_id_t	irq )

Convert a global IRQ ID to a local aon_timer IRQ type.

Parameters

dt	Instance of aon_timer.
irq	A PLIC ID that belongs to this instance.

Returns: The aon_timer IRQ, or kDtAonTimerIrqCount.

Note: This function assumes that the PLIC ID belongs to the instance of aon_timer passed in parameter. In other words, it must be the case that dt_aon_timer_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtAonTimerIrqCount.

Definition at line 116 of file dt_aon_timer.c.

◆ dt_aon_timer_irq_to_plic_id()

dt_plic_irq_id_t dt_aon_timer_irq_to_plic_id	(	dt_aon_timer_t	dt,
		dt_aon_timer_irq_t	irq )

Get the PLIC ID of a aon_timer IRQ for a given instance.

If the instance is not connected to the PLIC, this function will return kDtPlicIrqIdNone.

Parameters

dt	Instance of aon_timer.
irq	A aon_timer IRQ.

Returns: The PLIC ID of the IRQ of this instance.

Definition at line 106 of file dt_aon_timer.c.

		dt_aon_timer_memory_t	mem )

Get the base address of a memory.

Parameters

dt	Instance of aon_timer.
mem	The memory requested.

Returns: The base address of the requested memory.

Definition at line 92 of file dt_aon_timer.c.

		dt_aon_timer_memory_t	mem )

Get the size of a memory.

Parameters

dt	Instance of aon_timer.
mem	The memory requested.

Returns: The size of the requested memory.

Definition at line 99 of file dt_aon_timer.c.

◆ dt_aon_timer_reg_block()

uint32_t dt_aon_timer_reg_block	(	dt_aon_timer_t	dt,
		dt_aon_timer_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of aon_timer.
reg_block	The register block requested.

Returns: The register base address of the requested block.

Definition at line 85 of file dt_aon_timer.c.

◆ dt_aon_timer_reset()

dt_reset_t dt_aon_timer_reset	(	dt_aon_timer_t	dt,
		dt_aon_timer_reset_t	rst )

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

Parameters

dt	Instance of aon_timer.
rst	Reset port.

Returns: Reset signal.
