Buffered transmit mode
In buffered transmit mode (TX_MODE 0),
the 128 byte TXFIFO, located in
CC2420
RAM, is used to buffer data before
transmission.
A
preamble
(defined in the Frame Format section
below) is automatically inserted before the
length field during transmission. The
length field must always be the first byte
written to the transmit buffer for all frames.
sequence
Writing one or multiple bytes to the
TXFIFO is described in the FIFO access
section on page 29. Reading data from the
TXFIFO is possible with RAM access, but
this does not remove the byte from the
FIFO.
Transmission is enabled by issuing a
STXON
or
STXONCCA
command strobe.
See the Radio control state machine
section on page 42 for an illustration of
how the transmit command strobes affect
the state of
CC2420
. The
STXONCCA
strobe
is ignored if the channel is busy. See the
