4.1.3 BS signal mode
Connection to a CPU without the BS signal can be made via the BS_MODE signal. This setting can be
performed for all CPU modes. To connect to a CPU without the BS signal, set the BS_MODE signal to
“High” level.
When not using the BS signal, fix the BS pin of CORAL at “High” level.
When using the BS_MODE signal as “High” level, with the normally ready mode established, set the CPU
software wait to three cycles.

different from these descriptions.
