Used in NT/LT-S modes to enable or disable the multiframe structure (see
chapter 2.5.1.9)
1: S/T multiframe disabled
0: S/T multiframe enabled
Waiting for Acknowledge
This bit shows, if the last transmitted I-frame was acknowledged, i.e. V(A) = V(S)
(
The value written into the register bit is read.
Timer Recovery Status:
0: The device is not in the Timer Recovery state.
1: The device is in the Timer Recovery state.

Overflow
A "1" in this bit position indicates a message longer than 4095 bytes.
Four most significant bits of the total number of bytes in a received message.
Normally RBCH and RBCL should be read by the processor after an RME interrupt
1 ... B1 version
2 ... B2 version
3 ... V2.3 (B3) version
in order to determine the number of bytes to be read from the RFIFO, and the total
message length. The contents of the registers are valid only after an RME interrupt,
and remain so until the frame is acknowledged via the RMC bit.
WFA = 0) or was not yet acknowledged, i.e. V(A) < V(S) (
