BUSY_TX and RX_ON States
Reset Procedure
The transition from PLL_ON to BUSY_TX state and subsequent to RX_ON state is shown in
Figure 7-6 on page
Figure 7-6.
Starting from PLL_ON state it is further assumed that the PLL is already locked. A transmission
is initiated either by a rising edge of pin 11 (SLP_TR) or by command TX_START. The PLL set-
tles to the transmit frequency and the PA is enabled.
t
the internally generated SHR is transmitted. After that the PSDU data are transmitted from the
Frame Buffer.
After completing the frame transmission, indicated by IRQ_3 (TRX_END), the PLL settles back
to the receive frequency within t
If during TX_BUSY the radio transmitter is programmed to change to a receive state it automati-
cally proceeds the state change to RX_ON state after finishing the transmission.
The radio transceiver reset procedure is shown in
Figure 7-7.
