how to drive spi CS line low for 32 bits.

[arshdeep]

Hi,

Can you please direct me to the document that explains about generating more than 8 bits of clock in SPI and keeping CS line low for that entire period.

Also, if i have to send two 16bit data, would i have to send them in lots of 8bit ? or i can send them as 16bits using nrf_drv_spi_transfer API?

I am modifying the SPI example found under SDK15/example/peripheral/spi.

And i have to achieve the sequence attached in the image. 

Thank you

The Product Specification (aka "datasheet") is the document which describes the hardware capabilities & operation.

From there, you can either write your own driver, or use the driver provided in the SDK.

Write your own: www.8052mcu.com/.../160143

SDK documentation is here: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk/dita/sdk/sdk.html?cp=4

Specifically for hardware drivers:  http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/hardware_drivers.html?cp=4_0_0_2
