Receive Check enable.
A ’1’ enables, a ’0’ disables the receive frame length feature.
Receive Length.
The maximum receive length after which data reception is suspended can be
programmed in RL6..0. The maximum allowed receive frame length is
(RL + 1)
aborted by the opposite station (RME-interrupt, RAB-bit set (VFR in clock
mode 3)).
In this case the receive byte count (RBCH, RBCL) is greater than the
programmed receive length.
