Freescale Semiconductor
NOTE
For both graphs, the required IEEE 802.15.4 Standard accuracy and range
limits are shown. A 3.5 dBm offset has been programmed into the CCA
reporting level to center the level over temperature in the graphs.

Transmit Path Description
For the transmit path, the TX data that was previously written to the internal RAM is retrieved (packet
mode) or the TX data is clocked in via the SPI (stream mode), formed into packets per the 802.15.4 PHY,
spread, and then up-converted to the transmit frequency.
If the 802.15.4 modem is in packet mode, data is processed as an entire packet. The data is first loaded into
the TX buffer. The MCU then requests that the modem transmit the data. The MCU is notified via an
interrupt when the whole packet has successfully been transmitted.
