One frame could not be stored due to occupied RFIFO (i.e. whole frame has been lost). This
interrupt can be used for statistical purposes and indicates, that the CPU does not respond
quickly enough to an incoming RPF, or RME interrupt.
This is an early receiver interrupt activated after the start of a valid frame has been detected,
i.e. after a valid address check in operation modes providing address recognition, otherwise
after the opening flag (transparent mode 0), delayed by two bytes.
After an RFS interrupt, the contents of
Indicates, that a state transition has occurred at the CTS pin. The actual state can be read
from STAR register (CTS bit).
This interrupt must be enabled setting the CIE bit in CCR2.
