nordic,nrf-uart

Vendor: Nordic Semiconductor

Description

These nodes are “uart” bus nodes.

Nordic nRF family UART.

This is the binding for the peripheral without EasyDMA support.
See the "nordic,nrf-uarte" binding for UARTE, i.e. UART with
EasyDMA.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

tx-pin

int

 
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.

rx-pin

int

 
The RX pin to use. The pin numbering scheme is the same as the
tx-pin property's.

rts-pin

int

 
The RTS pin to use. The pin numbering scheme is the same as the
tx-pin property's.

cts-pin

int

 
The CTS pin to use. The pin numbering scheme is the same as the
tx-pin property's.

current-speed

int

 
Initial baud rate setting for UART. Only a fixed set of baud
rates are selectable on these devices.

Legal values: 1200, 2400, 4800, 9600, 14400, 19200, 28800, 31250, 38400, 56000, 57600, 76800, 115200, 230400, 250000, 460800, 921600, 1000000

rx-pull-up

boolean

 
Enable pull-up resistor on the RX pin.

cts-pull-up

boolean

 
Enable pull-up resistor on the CTS pin.

clock-frequency

int

 
Clock frequency information for UART operation

hw-flow-control

boolean

 
Set to enable RTS/CTS flow control at boot time

parity

string

 
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: 'none', 'odd', 'even'
