Handshake
The state is changed with
every new job. It is controlled by the
master only, when a new job is to be
processed by the R1000. The R1000
mirrors the handshake back, once the job
is processed. At a successful job, the
collision bit is set to 0, otherwise the
collision bit is set by the R1000 to 1.
Further jobs can only be done by
withdrawal of the faulty service.
BOUT0.6
Handshake
The state is changed with every
new job. It is controlled by the master only,
when a new job is to be processed by the
R1000. The R1000 mirrors the handshake
back, once the job is processed. At a successful
job, the collision bit is set to 0, otherwise the
collision bit is set by the R1000 to 1. Further
jobs can only be done by withdrawal of the
faulty service.

BOUT0.7
Collision
0 = Fault free access, 1 = Faulty access.
"1" is set by the R1000 only if a service is
invalid or not executable. In this case the
master must reset the service to end the faulty
condition. See also the section "Reset faulty
access" within this chapter.
