RFIFOB
A read access to this register gives access to the “current” FIFO location selected by an
internal pointer which is automatically incremented after each read access.
The RFIFOB contains up to 128 bytes of received data.
After an ISTAB.RPF interrupt, a complete data block is available. The block size can be
8 or 16 bytes depending on the EXMB.RFBS setting.
After an ISTAB.RME interrupt, the number of received bytes can be obtained by reading
the RBCLB register.
4.6.16
XFIFOB
A write access to this register gives access to the “current” FIFO location selected by an
internal pointer which is automatically incremented after each write access.
The total XFIFO size is 128 byte and data blocks with up to 32 bytes of transmit data can
be written to the XFIFOB following an ISTAB.XPR interrupt.
