The device responds to an idle flag one bit time too early.

Description:

This causes problems in a loop-mode network. It only occurs in loop mode when

using an external SIU clock source and idle flags.

Workaround:

None.

Errata No. 4

Problem:

Under certain conditions the SIU will overwrite the RCB register when starting a

transmission.

Description:

The conditions are:

The SIU is externally clocked.

The SIU is in flexible mode.

The CPU has not already read the RCB from a previous reception before the

transmission takes place.

Workaround:

Read the RCB before initiating a transmit.
