nRF24L01 Product Specification
The data and control interface gives you access to all the features in the nRF24L01. The data and control
interface consists of the following six 5Volt tolerant digital signals:
You can use the SPI to activate the nRF24L01 data FIFOs or the register map by 1 byte SPI commands
during all modes of operation.
8.1
8.2
The SPI is a standard SPI with a maximum data rate of 8Mbps.
8.3
This chapter describes the SPI commands and SPI timing.
8.3.1
The SPI commands are shown in
tion on CSN.
In parallel to the SPI command word applied on the MOSI pin, the STATUS register is shifted serially out on
the MISO pin.
The serial shifting SPI commands is in the following format:
<Command word: MSBit to LSBit (one byte)>
<Data bytes: LSByte to MSByte, MSBit in each byte first>
