Note: All bytes stored in the RFIFO are relevant for the receive length check feature including
the receiver status byte.
RL … Receive Length
The maximum receive length after which data reception is suspended can be programmed
here. Depending on the value RL programmed via RL6 … RL0, the receive length is
(RL + 1) × 32 bytes! A frame exceeding this length is treated as if it was aborted by the
opposite station (RME Interrupt, RAB bit set).
In this case, the Receive Byte Count (RBCH, RBCL) is greater than the programmed
receive length.
