|
|
Enable loopback mode on LPUART peripheral. When present, RX pin is
disconnected, and transmitter output is internally connected to
the receiver input.
|
|
|
Set to enable RTS signal, which can be used to enable the driver
of an external RS-485 transceiver. Note hw-flow-control should be
set to false.
|
|
|
RTS polarity at RS485 mode.
|
|
|
Clock frequency information for UART operation
|
|
|
Initial baud rate setting for UART
|
|
|
Set to enable RTS/CTS flow control at boot time
|
|
|
Configures the parity of the adapter. Enumeration id 0 for none, 1 for odd
and 2 for even parity. Default to none if not specified.

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
