Low power modes
This application note gives an overview of the CA-821X IEEE® 802.15.4 transceiver modem low power modes, how they can be programmed and used in combination with a host microcontroller (MCU). It explains the different levels of low power modes, the wake-up conditions and the required steps to re-initialise the CA-821X for normal operation. Code examples (in C) are given independently of the host MCU.
