Appendix B
HSCX Auto-Mode: Specific Points
HSCX auto-mode of SAB 82525/SAB 82520 (HSCX/HSCC) is optimized for a window size of
one. Therefore the following simplifications are made:
Two Byte Addresses:
Semiconductor Group
No REJ-frame is generated, an RR-frame will be transmitted instead. If a REJ-frame is
received it will be handled like an RR-frame.
The transmit/receive variables N(R)/N(S) are checked within the window size (i.e. one),
only the LSB is evaluated.
An I-frame with an incorrect N(R)-value is not accepted, an error interrupt (EXIR:PCE) is
generated.
The timer recovery state is cancelled if a positive acknowledgement (updated N(R)) is
received.
Selective reject is treated like RR.
After sending an I-frame the HSCX cannot transmit any frame before an
acknowledgement or an XRES-command.
An I-frame with C = 0 is accepted without error indication.
