MPU or XDATA space is the address range for the MPU XRAM (0x00 to 0x7F). Addresses

4.4 Auxiliary Commands
4.4.1 Repeat Command
The repeat command can be useful for monitoring measurements and is efficient in demands from the
host.
If the host requests line frequency, alarm status, Irms nb overcurrent event count, Vrms SAG event count,
Vrms overvoltage event count, voltage, power, and accumulated energy measurements for Outlet 1 with
the following command string:
>)01????????
If the host then desires this same request without issuing another command, the repeat command can be
used:
>, (no carriage return needed for the repeat command)
The host only needs to send one character rather than an entire string.
