PRODUCT SPECIFICATION
nRF2402/nRF2402G Single Chip 2.4 GHz Radio Transmitter
Note that the configuration word will be lost when VDD is turned off and that the device then
must be configured before going to active mode. If the device is configured one can go
directly from power down to active mode.
Note:
CE and CS may not be high at the same time. Setting one or the other decides whether
configuration or active mode is entered.
Configuration Mode
In configuration mode the transmitters output power, transmit frequency, data rate, CRC, and
preamble is set. The configuring data will be loaded during the Chip Select period (CS="1").
A random number of bits between 1 and 20 may be shifted in to the register to configure the
transmitter, but normally you would at least shift in the seven channel frequency bits. The
new configuration is activated on the negative edge of CS.
When one or more of the bits in the configuration word needs to be changed the following
timing apply.

If configuration mode is entered from power down, CS can be set high after Tpd2sby as
shown in Figure 10.
