nRF24LE1 Preliminary Product Specification
nRF24LE1 features a double buffered Serial Peripheral Interface (SPI). You can configure it to work in all
four SPI modes. The default is mode 0.
The SPI connects to the following pins of the device: MMISO , MMOSI , MSCK , SCSN , SMISO , SMOSI and
SSCK ..
The SPI Master function does not generate any chip select signal (CSN). The programmer typically uses
another programmable digital I/O to act as chip selects for one or more external SPI Slave devices.
