During startup from SLEEP or RESET, the radio transceiver issues an TRX24_AWAKE
interrupt when it enters state TRX_OFF.
If the microcontroller initiates an energy-detect (ED) or clear-channel-assessment
(CCA) measurement, the completion of the measurement is indicated by interrupt
TRX24_CCA_ED_DONE, refer to sections
"Clear Channel Assessment (CCA)" on page 71
After RESET all interrupts are disabled. During radio transceiver initialization it is
recommended to enable AWAKE to be notified once the TRX_OFF state is entered.
Note that the TRX24_AWAKE interrupt can usually not be seen when the transceiver
enters TRX_OFF state after RESET, because register IRQ_MASK is reset to mask all
interrupts. In this case, state TRX_OFF is normally entered before the microcontroller
could modify the register.
The interrupt handling in Extended Operating Mode is described in section
Handling" on page
The ATmega128RFA1 Transceiver module can be identified by four registers
(PART_NUM, VERSION_NUM, MAN_ID_0, MAN_ID_1). One register contains a
unique part number and one register the corresponding version number. Two additional
registers contain the JTAG manufacture ID. The transceiver identification registers are
provided for compatibility to the transceiver only device.
A unique device identification is also possible with the three AVR signature bytes. For
details about accessing this information refer to
Note:
Description
Indicates radio transceiver reached TRX_OFF
state RESET, or SLEEP states
Indicates the completion of a frame
transmission
Indicates address matching
Indicates the end of a CCA or ED
measurement
Indicates the completion of a frame reception
Indicates the start of a PSDU reception. The
TRX_STATE changes to BUSY_RX, the PHR
is ready to be read from Frame Buffer
Indicates PLL unlock. If the radio transceiver
is in BUSY_TX / BUSY_TX_ARET state, the
PA is turned off immediately
Indicates PLL lock
1. The lowest IRQ Number has the highest priority.
