Initialization

PHY_INIT

This command sequence is executed in order to bring the radio transceiver to the basic state TRX_OFF after power on. Nevertheless this sequence can safely be executed from any state.

After the reset, the hardware identification data are read. All interrupts will be disabled (RG_IRQ_MASK = 0) and a dummy read of the register RG_IRQ_STATUS is done, in order to avoid the occurence of unhandled interrupts, before the chip is started. In the case, that the radio transceiver is in state P_ON, when this sequence is executed, the state TRX_OFF is reached typically 510 us (refer to AT86RF230 data sheet) after CMD_TRX_OFF is written to the sub register SR_TRX_CMD.
