TX PROCESSING IN BUFFERED MODE (FSIZE = 16, TXSTIRQ0 = 0))
3.10.2
RX PROCESSING
After entering RX in Buffered mode, the MRF89XA
requires the host microcontroller to get the received
data from the FIFO. The FIFO starts to be filled with
received bytes either when a Sync Word has been
detected (in this case only the bytes following the Sync
Word are filled into the FIFO) or when the FIFOFSC bit
(FPPRIREG<6>) is issued by the user depending on
the state of bit, FIFOFM (FTPRIREG<7>).
In Buffered mode, the packet length is not limited (that
is, as long as FIFOFSC is set, the received bytes are
shifted into the FIFO).
The host microcontroller software must therefore
manage the transfer of the FIFO contents by interrupt
and ensure reception of the correct number of bytes. In
this mode, even if the remote transmitter has stopped,
the demodulator outputs random bits due to noise.
When the FIFO is full, the FIFOFULL IRQ (source) is
issued to alert the host microcontroller that at that time,
the FIFO can still be unfilled without data loss. If the
FIFO is not unfilled, after the SR is full (that is, 8 bits
periods later), FOVRRUN is asserted and the SR’s
content is lost.
Figure 3-23 illustrates RX processing with a 16-byte
FIFO size and FIFOFSC = 0. Note that in the example
of Section 3.10.5, Buffered Mode Example, the host
microcontroller does not retrieve any bytes from the
FIFO through SPI data interface, causing an overrun.
