Data Fields
uint32_t	base_addr[kDtRomCtrlRegBlockCount]	Base address of each register block.
dt_clock_t	clock[kDtRomCtrlClockCount]	Clock signal connected to each clock port.
top_darjeeling_alert_id_t	first_alert	Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler.
top_earlgrey_alert_id_t	first_alert	Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler.
dt_instance_id_t	inst_id	Instance ID.
dt_reset_t	reset[kDtRomCtrlResetCount]	Reset signal connected to each reset port.

Macro Definition Documentation

TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({     if ((dt) < (dt_rom_ctrl_t)0 || (dt) >= kDtRomCtrlCount)       return (default);     &rom_ctrl_desc[dt];   })

Return a pointer to the dt_rom_ctrl_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_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 74 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.

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 59 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 64 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.
