accessing method, if there are data in RXFIFO, the top word is returned and

the RXFIFO depth is decreased by 1. In half-word accessing method, two SPI

bursts are returned and the RXFIFO depth is decrease by 2. In word

accessing method, the four SPI bursts are returned and the RXFIFO depth is

decreased by 4.

Note: This address is read-only if RF_TEST is ‘0’, and if RF_TEST is set to ‘1’,

this address is readable and writable to test the RX FIFO through the AHB

bus.
