number of bits per time-slot is programmable in register XCCR.
Transmit bit Shift bit2-1.
Together with XCS0 in register CCR2 the transmit bit shift can be adjusted.
TSNX4
Receive Byte Count.
Together with RBCH (bits RBC11-RBC8), the length of the actual received
frame (0…4095 bytes) can be determined. These registers must be read by
the CPU following a RME interrupt.
Counter Overflow.
A ‘1’ indicates that more than 4095 bytes were received.
The received frame exceeded the byte count in RBC11…RBC0.
Together with RBCL (bits RBC7…RBC0) the length of the received frame
can be determined.
