Function Documentation

dt_ast_clock()

dt_clock_t dt_ast_clock	(	dt_ast_t	dt,
		dt_ast_clock_t	clk )

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

Parameters

dt	Instance of ast.
clk	Clock port.

Returns

Clock signal.

Definition at line 83 of file dt_ast.c.

dt_ast_from_instance_id()

dt_ast_t dt_ast_from_instance_id

(

dt_instance_id_t

inst_id

)

Get the ast instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id

Instance ID.

Returns

A ast instance.

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

Definition at line 61 of file dt_ast.c.

dt_ast_instance_id()

dt_instance_id_t dt_ast_instance_id

(

dt_ast_t

dt

)

Get the instance ID of an instance.

Parameters

dt	Instance of ast.

Returns

The instance ID of that instance.

Definition at line 68 of file dt_ast.c.

dt_ast_reg_block()

uint32_t dt_ast_reg_block	(	dt_ast_t	dt,
		dt_ast_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of ast.
reg_block	The register block requested.

Returns

The register base address of the requested block.

Definition at line 73 of file dt_ast.c.

dt_ast_reset()

dt_reset_t dt_ast_reset	(	dt_ast_t	dt,
		dt_ast_reset_t	rst )

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

Parameters

dt	Instance of ast.
rst	Reset port.

Returns

Reset signal.
