PRODUCT SPECIFICATION
nRF9E5 Single Chip Transceiver with Embedded Microcontroller and ADC
11 TRANSCEIVER AND AD CONVERTER CONFIGURATION
All configuration of the transceiver and AD converter subsystem is done via an internal
SPI -interface of the two systems. The interface consists of 7 registers, a SPI instructions
set is used to decide which operation shall be performed. The SPI-interface can only be
activated when the transceiver is in standby mode. All references to the SPI interface in
this chapter refer to the internal SPI interface of the transceiver and AD converter
subsystem.
11.1 Internal SPI Register Configuration
The SPI-interface consists of seven internal registers. A register read-back mode is
implemented to allow verification of the register contents
