RMC200 Registers, Files 512-575: Plot Status/Configuration

The following files contain the Plot Configuration registers. See the Reading Plots with a Host Controller topic for details on how some of them can be used.

n = plot # (0-63)

The CPU20L supports 48 plots. The CPU40 supports 64 plots with firmware 1.14.0 or newer, and 32 plots with older firmware.
