How to configure the SPI function for D0 and D18 of JN5169

Dear Sir,

Hello, I want to use the DO0 pin and DIO18 pin to configure them as
SCLK and SPIMOSI function. What should I do?

Thank you.

Hello.

According to the JN5169 datasheet, when the device reset is active, all the SPI-bus master pins are configured as inputs with their pull-up resistors active. The pins stay in this state until the SPI-bus master block is enabled.

Control of the SPI Master using functions of the integrated API is described in JN516x Integrated Peripherals API User Guide, Chapter 14 Serial Peripheral Interface (SPI) Master. Section 14.5 describes how to use the API functions to operate the SPI.

Regards,
Eduardo.
