Function Documentation

dt_rom_ctrl_alert_from_alert_id()

dt_rom_ctrl_alert_t dt_rom_ctrl_alert_from_alert_id	(	dt_rom_ctrl_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns

The rom_ctrl alert, or kDtRomCtrlAlertCount.

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

Definition at line 85 of file dt_rom_ctrl.c.

dt_rom_ctrl_alert_to_alert_id()

dt_alert_id_t dt_rom_ctrl_alert_to_alert_id	(	dt_rom_ctrl_t	dt,
		dt_rom_ctrl_alert_t	alert )

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

Returns

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

Definition at line 79 of file dt_rom_ctrl.c.

dt_rom_ctrl_clock()

dt_clock_t dt_rom_ctrl_clock	(	dt_rom_ctrl_t	dt,
		dt_rom_ctrl_clock_t	clk )

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

Parameters

dt	Instance of rom_ctrl.
clk	Clock port.

Returns

Clock signal.

Definition at line 97 of file dt_rom_ctrl.c.

dt_rom_ctrl_from_instance_id()

dt_rom_ctrl_t dt_rom_ctrl_from_instance_id

(

dt_instance_id_t

inst_id

)

Get the rom_ctrl instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id

Instance ID.

Returns

A rom_ctrl instance.

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

Definition at line 59 of file dt_rom_ctrl.c.

dt_rom_ctrl_instance_id()

dt_instance_id_t dt_rom_ctrl_instance_id

(

dt_rom_ctrl_t

dt

)

Get the instance ID of an instance.

Parameters

dt	Instance of rom_ctrl.

Returns

The instance ID of that instance.

Definition at line 66 of file dt_rom_ctrl.c.

dt_rom_ctrl_reg_block()

uint32_t dt_rom_ctrl_reg_block	(	dt_rom_ctrl_t	dt,
		dt_rom_ctrl_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of rom_ctrl.
reg_block	The register block requested.

Returns

The register base address of the requested block.

Definition at line 71 of file dt_rom_ctrl.c.

dt_rom_ctrl_reset()

dt_reset_t dt_rom_ctrl_reset	(	dt_rom_ctrl_t	dt,
		dt_rom_ctrl_reset_t	rst )

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

Parameters

dt	Instance of rom_ctrl.
rst	Reset port.

Returns

Reset signal.
