This document describes the issue of disappearing IDLE in Beta systems and provides a workaround
The document provides errata information for the TSB41BA3B component, detailing a specific problem observed in Beta systems with more than four cable hops. The issue, described as a disappearing IDLE between a data packet and an arbitration grant, can lead to max arbitration state timeout and bus reset.
The recommended workaround is to add a 1394A PHY to the system, which forces legacy gap timing on the 1394 bus and prevents the IDLE from disappearing.
It addresses a disappearing IDLE in a Beta system that results in max arbitration state timeout and bus reset.
