Description
Read-only registers
Read and write registers
Update buffer for this bit is present. If an update is issued and the Update
Register Access bit (UPD in Command Word) is set, the immediate values
are stored in this update buffer simultaneously. This enables a snapshot of
all necessary system parameters at the same time.
