FIFO access
The TXFIFO and RXFIFO may be
accessed through the TXFIFO (0x3E) and
RXFIFO (0x3F) registers.
The TXFIFO is write only, but may be read
back using RAM access as described in
written one byte at a time, as with RAM
access. The RXFIFO is both writeable and
readable. Writing to the RXFIFO should
however only be done for debugging or for
using the RXFIFO for security operations
(decryption / authentication).
The crystal oscillator must be running
when accessing the FIFOs.
When writing to the TXFIFO, the status
byte (see Table 5) is output for each new
data byte on
SO
, as shown in Figure 8.
This could be used to detect TXFIFO
underflow (see section RF Data Buffering
section on page 37) while writing data to
the TXFIFO.
Multiple FIFO bytes may be accessed in
one operation, as with the RAM access.
FIFO access can only be terminated by
setting the
CSn
pin high once it has been
started.
The
FIFO
and
FIFOP
pins also provide
additional information on the data in the
receive FIFO, as will be described in the
Microcontroller
Interface
Description section on page 30. Note that
the
FIFO
and
FIFOP
pins only apply to
the RXFIFO. The TXFIFO has its
underflow flag in the status byte.
and
Pin
The TXFIFO may be flushed by issuing a
STXFLUSH
command strobe. Similarly, a
SRXFLUSH
command strobe will flush the
receive FIFO.
Multiple SPI access
Register access, command strobes, FIFO
access and RAM access may be issued
continuously without setting
CSn
high.
E.g. the user may issue a command
strobe, a register write and writing 3 bytes
to the TXFIFO in one operation, as
