... The precondition for data reception is a valid preamble. The receiver is continuously searching for a valid telegram and receives the data if all preconfigured checks are successfully passed. The RXMode is usually enabled by SPI command, or directly after power-on, when selected in the EEPROM setting. Atmel ATA5830/ATA5830N 14 Figure 2-1. ...

... During IDLEMode(RC) and IDLEMode(XTO) the AVR microcontroller will enter a sleep mode to reduce the current consumption. The sleep mode of the microcontroller section can be defined in the EEPROM. To achieve the optimum current consumption the power-down mode is recommended. 2. Only activated applications. This is selectable in the EEPROM setting. Atmel ATA5830/ATA5830N DVCC AVCC VS_PA off ...
