I want to implement spi communication and TWI communication on 2 IO pins.

[odenwar]

I am developing a NRF52810 product,
I am downloading using JTAK on NRF52832 development board.

I have the NRF52810 because of the lack of IO pins.
SPI CLK , TWI CLK are pin P0.12,
SPI MOSI, TWI Data is pin P0.15,
I want to control the SPI CS pin with pin P0.04.

How can I implement this feature?

Hi.

from nRF side, you can configure both modules (nrfx_twim and nrfx_swim) at same pins, and switch between them, just don't forget to call uninit() of one module before calling init() of another one. But if you share I/O lines between i2c and spi, you need some switching/blocking schematic for i2c bus.
