5.8.3

Packet Handling in Transmit Mode

The payload that is to be transmitted must be written into the TX FIFO. The first byte written must be the
length byte when variable packet length is enabled. The length byte has a value equal to the payload of
the packet (including the optional address byte). If fixed packet length is enabled, then the first byte written
to the TX FIFO is interpreted as the destination address, if this feature is enabled in the device that
receives the packet.

The modulator will first send the programmed number of preamble bytes. If data is available in the TX
FIFO, the modulator will send the two-byte (optionally 4-byte) sync word and then the payload in the TX
FIFO. If CRC is enabled, the checksum is calculated over all the data pulled from the TX FIFO and the
result is sent as two extra bytes at the end of the payload data. If the TX FIFO runs empty before the
complete packet has been transmitted, the radio will enter TXFIFO_UNDERFLOW state. The only way to
exit this state is by issuing an SFTX strobe. Writing to the TX FIFO after it has underflowed will not restart
TX mode.

If whitening is enabled, the length byte, payload data and the two CRC bytes will be whitened. This is
done

before

the

optional

FEC/Interleaver

stage.

Whitening

is

enabled

by

setting

PKTCTRL0.WHITE_DATA=1.

If FEC/Interleaving is enabled, the length byte, payload data and the two CRC bytes will be scrambled by
the

interleaver,

and

FEC

encoded

before

being

modulated.

FEC

is

enabled

by

setting

MDMCFG1.FEC_EN=1.

5.8.4

Packet Handling in Firmware

When implementing a packet oriented radio protocol in firmware, the MCU needs to know when a packet
has been transmitted. Additionally, for packets longer than 64 bytes, the TX FIFO needs to be refilled
while in TX. This means that the MCU needs to know the number of bytes that can be written to the TX
FIFO. There are two possible solutions to get the necessary status information:

a. Interrupt Driven Solution

–

The GDO pins can be used in TX to give an interrupt when a sync word has been transmitted or
when a complete packet has been transmitted by setting IOCFGx.GDOx_CFG=0x06. In addition,
there are two configurations for the IOCFGx.GDOx_CFG register that can be used as an interrupt
source to provide information on how many bytes that is in the TX FIFO. The
IOCFGx.GDOx_CFG=0x02 and the IOCFGx.GDOx_CFG=0x03 configurations are associated with
the TX FIFO. See

Table 5-10

for more information.

b. SPI Polling

–

The PKTSTATUS register can be polled at a given rate to get information about the current GDO2
and GDO0 values respectively. The TXBYTES register can be polled at a given rate to get
information about the number of bytes in the TX FIFO. Alternatively, the number of bytes in the TX
FIFO can be read from the chip status byte returned on the MISO line each time a header byte,
data byte, or command strobe is sent on the SPI bus.
