Receive frame start Enable.
When set, the RFS-interrupt in register EXIR_A/B is enabled.
Channel Configuration Register 2 (CCR2)
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) × 32 bytes. A frame exceeding this length is treated as if it was
aborted by the opposite station (RME-interrupt, RAB-bit set (VFR )).
In this case the receive byte count (RBCH, RBCL) is greater than the
programmed receive length.
Transmit Data Overflow.
A ‘1’ indicates, that more than 32 bytes have been written into the XFIFO.
XFIFO Write enable.
A ‘1’ indicates, that data can be written into the XFIFO.
