Pressure value

There are three pressure values in the Sakura V1 protocol: P1, P2, and P3. They are by
default configured as:
• P1: Liquid pressure
• P2: Middle pressure
• P3: Vapor pressure
For backward compatibility with Rosemount Rex, the Liquid pressure value can be
remapped to P2 and/or P3. This is done in holding register Sakura_PressConf (1214). If
Liquid pressure is remapped, Vapor pressure will be used for the other pressure requests
that are not remapped.
