Function Documentation

◆ dt_pinmux_alert_from_alert_id()

dt_pinmux_alert_t dt_pinmux_alert_from_alert_id ( dt_pinmux_t dt,
dt_alert_id_t alert )

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

Parameters
dtInstance of pinmux.
alertA global alert ID that belongs to this instance.
Returns
The pinmux alert, or kDtPinmuxAlertCount.

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

Definition at line 87 of file dt_pinmux.c.

◆ dt_pinmux_alert_to_alert_id()

dt_alert_id_t dt_pinmux_alert_to_alert_id ( dt_pinmux_t dt,
dt_pinmux_alert_t alert )

Get the alert ID of a pinmux 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
dtInstance of pinmux.
alertA pinmux alert.
Returns
The Alert Handler alert ID of the alert of this instance.

Definition at line 81 of file dt_pinmux.c.

◆ dt_pinmux_clock()

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

Parameters
dtInstance of pinmux.
clkClock port.
Returns
Clock signal.

Definition at line 99 of file dt_pinmux.c.

◆ dt_pinmux_from_instance_id()

dt_pinmux_t dt_pinmux_from_instance_id ( dt_instance_id_t inst_id)

Get the pinmux instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters
inst_idInstance ID.
Returns
A pinmux instance.

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

Definition at line 61 of file dt_pinmux.c.

◆ dt_pinmux_instance_id()

dt_instance_id_t dt_pinmux_instance_id ( dt_pinmux_t dt)

Get the instance ID of an instance.

Parameters
dtInstance of pinmux.
Returns
The instance ID of that instance.

Definition at line 68 of file dt_pinmux.c.

◆ dt_pinmux_reg_block()

Get the register base address of an instance.

Parameters
dtInstance of pinmux.
reg_blockThe register block requested.
Returns
The register base address of the requested block.

Definition at line 73 of file dt_pinmux.c.

◆ dt_pinmux_reset()

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

Parameters
dtInstance of pinmux.
rstReset port.
Returns
Reset signal.
