After an ISTAH.RME interrupt, the number of received bytes can be obtained by reading
the RBCL register.
7.0.1
XFIFO
A write access to any address within the range 00-1F
location selected by an internal pointer which is automatically incremented after each
write access. This allows the use of efficient “move string” type commands by the
microcontroller.
Depending on EXMR.XFBS up to 16 or 32 bytes of transmit data can be written to the
XFIFO following an ISTAH.XPR interrupt.
