  • After you enter register read ${variable name}, the register value on the current device is returned. If multiple registers are read at a time, separate them with spaces.
    • The register value is returned when the variable name is available on the current device.
    • Invalid register name 'variable name' is returned when the variable name is not available on the current device.
