Using QSPI as traditional SPI

[leoc7]

Hi everyone,

My hw/sw configuration:

- nRF52840

- sdk 15.0.0

- softdevice: s140_nrf52_6.0.0

I need to use 2 SPI and 2 I2C interfaces.

Nrf52840 has

- 3 SPI (spi0, 1, 2)

- 2 I2C (i2c0, 1)

- 1 QSPI

If I use the 2 I2C interfaces, i can’t use spi0 and spi1.

In this way, there is only 1 SPI available (spi3).

Is there a way to use QSPI as a traditional SPI?

Many thanks!

The nRF52840 has 4 SPI interfaces, see the PS where SPI 0 and 1 share the base address with TWI 0 and 1.

QSPI can't be used as normal SPI.

Many thanks! Sorry for this lack!
In this way, I can use TWI0, TWI1 and SPI2, SPI3 concurrently! Is it correct?

Correct!
