VN3 … VN0 … Version Number of Chip
Received Byte Count High (READ)
Value after RESET: 000xxxxx
RBCH
RBC11 … RBC8 … Receive Byte Count (most significant bits)
CD … Carrier Detect
DMA, NRM, CAS … These bits represent the read-back value programmed in XBCH
(see XBCH!)
OV … Counter Overflow
Version Status Register (READ)
VSTR
Semiconductor Group
This bit represents the inverted state at the CD (A CLK) pin even when CAS is not enabled.
1 … CD active (low)
0 … CD inactive (high)
0:000 … Version A1
2:010 … Version A2
4:100 … Version A3
5:101 … Version 2.1
Together with RBCL (bits RBC7 … RBC0) the length of the received frame can be
determined.
More than 4095 bytes received!
The received frame exceeded the byte count in RBC11 … RBC0.
