Macro Definition Documentation

◆ TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({ if ((dt) < (dt_pattgen_t)0 || (dt) >= kDtPattgenCount) return (default); &pattgen_desc[dt]; })

Return a pointer to the dt_pattgen_desc_t structure of the requested dt if it's a valid index.

Otherwise, this macro will return (i.e. exit the function) with the provided default value.

Function Documentation

◆ dt_pattgen_alert_from_alert_id()

dt_pattgen_alert_t dt_pattgen_alert_from_alert_id	(	dt_pattgen_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns: The pattgen alert, or kDtPattgenAlertCount.

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

Definition at line 170 of file dt_pattgen.c.

◆ dt_pattgen_alert_to_alert_id()

dt_alert_id_t dt_pattgen_alert_to_alert_id	(	dt_pattgen_t	dt,
		dt_pattgen_alert_t	alert )

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

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

Definition at line 164 of file dt_pattgen.c.

◆ dt_pattgen_clock()

dt_clock_t dt_pattgen_clock	(	dt_pattgen_t	dt,
		dt_pattgen_clock_t	clk )

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

Parameters

dt	Instance of pattgen.
clk	Clock port.

Returns: Clock signal.

Definition at line 188 of file dt_pattgen.c.

◆ dt_pattgen_from_instance_id()

dt_pattgen_t dt_pattgen_from_instance_id ( dt_instance_id_t inst_id )

Get the pattgen instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id Instance ID.

Returns: A pattgen instance.

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

Definition at line 106 of file dt_pattgen.c.

◆ dt_pattgen_instance_id()

dt_instance_id_t dt_pattgen_instance_id ( dt_pattgen_t dt )

Get the instance ID of an instance.

Parameters

dt	Instance of pattgen.

Returns: The instance ID of that instance.

Definition at line 113 of file dt_pattgen.c.

◆ dt_pattgen_irq_from_plic_id()

dt_pattgen_irq_t dt_pattgen_irq_from_plic_id	(	dt_pattgen_t	dt,
		dt_plic_irq_id_t	irq )

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

Parameters

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

Returns: The pattgen IRQ, or kDtPattgenIrqCount.

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

Definition at line 149 of file dt_pattgen.c.

◆ dt_pattgen_irq_to_plic_id()

dt_plic_irq_id_t dt_pattgen_irq_to_plic_id	(	dt_pattgen_t	dt,
		dt_pattgen_irq_t	irq )

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

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

Parameters

dt	Instance of pattgen.
irq	A pattgen IRQ.

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

Definition at line 139 of file dt_pattgen.c.

◆ dt_pattgen_memory_base()

uint32_t dt_pattgen_memory_base	(	dt_pattgen_t	dt,
		dt_pattgen_memory_t	mem )

Get the base address of a memory.

Parameters

dt	Instance of pattgen.
mem	The memory requested.

Returns: The base address of the requested memory.

Definition at line 125 of file dt_pattgen.c.

◆ dt_pattgen_memory_size()

uint32_t dt_pattgen_memory_size	(	dt_pattgen_t	dt,
		dt_pattgen_memory_t	mem )

Get the size of a memory.

Parameters

dt	Instance of pattgen.
mem	The memory requested.

Returns: The size of the requested memory.

Definition at line 132 of file dt_pattgen.c.

dt_periph_io_t dt_pattgen_periph_io	(	dt_pattgen_t	dt,
		dt_pattgen_periph_io_t	sig )

Get the peripheral I/O description of an instance.

Parameters

dt	Instance of pattgen.
sig	Requested peripheral I/O.

Returns: Description of the requested peripheral I/O for this instance.

Definition at line 181 of file dt_pattgen.c.

◆ dt_pattgen_reg_block()

uint32_t dt_pattgen_reg_block	(	dt_pattgen_t	dt,
		dt_pattgen_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of pattgen.
reg_block	The register block requested.

Returns: The register base address of the requested block.

Definition at line 118 of file dt_pattgen.c.

◆ dt_pattgen_reset()

dt_reset_t dt_pattgen_reset	(	dt_pattgen_t	dt,
		dt_pattgen_reset_t	rst )

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

Parameters

dt	Instance of pattgen.
