The TX pin to use.
For pins P0.0 through P0.31, use the pin number. For example,
to use P0.16 for TX, set:
tx-pin = <16>;
For pins P1.0 through P1.31, add 32 to the pin number. For
example, to use P1.2 for TX, set:
tx-pin = <34>; /* 32 + 2 */
This property is required. |
|
|
The RX pin to use. The pin numbering scheme is the same as the
tx-pin property's.
|
|
|
The RTS pin to use. The pin numbering scheme is the same as the
tx-pin property's.
|
|
|
The CTS pin to use. The pin numbering scheme is the same as the
tx-pin property's.
|
|
|
Initial baud rate setting for UART. Only a fixed set of baud
rates are selectable on these devices.
Legal values: |
|
|
Enable pull-up resistor on the RX pin.
|
|
|
Enable pull-up resistor on the CTS pin.
|
|
|
Clock frequency information for UART operation
|
|
|
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.
Legal values: |
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-uarte” compatible.

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.
