The number of bytes in the RX FIFO can also
be
read
from
the
status
register
RXBYTES.NUM_RXBYTES. If a received data
byte is written to the RX FIFO at the exact
same time as the last byte in the RX FIFO is
read over the SPI interface, the RX FIFO
pointer is not properly updated and the last
read byte will be duplicated. To avoid this
problem, the RX FIFO should never be
emptied before the last byte of the packet is
received.
For packet lengths less than 64 bytes it is
recommended to wait until the complete
packet has been received before reading it out
of the RX FIFO.
If the packet length is larger than 64 bytes, the
MCU must determine how many bytes can be
read
from
the
RX
FIFO
The
following
software routine can be used:
1. Read
repeatedly at a rate specified to be at least
twice that of which RF bytes are received
until the same value is returned twice;
store value in
n.
2.
If n < # of bytes remaining in packet, read
n-1 bytes from the RX FIFO.
3.
Repeat steps 1 and 2 until n = # of bytes
remaining in packet.
4.
Read the remaining bytes from the RX
FIFO.
The 4-bit FIFOTHR.FIFO_THR setting is used
to program threshold points in the FIFOs.
Table 28 lists the 16 FIFO_THR settings and
the corresponding thresholds for the RX FIFO.

Table 28:
FIFO_THR Settings and the
Corresponding RX FIFO Thresholds
A signal will assert when the number of bytes
in the RX FIFO is equal to or higher than the
programmed threshold. This signal can be
viewed on the GDO pins (see Table 29 on
page 42).
Figure 24 shows the number of bytes in the
RX FIFO when the threshold signal toggles in
the case of FIFO_THR=13. Figure 25 shows
the signal on the GDO pin as the RX FIFO is
filled above the threshold, and then drained
below in the case of FIFO_THR=13.
