Example: A meter designed with VMAX=600V and IMAX=208A is supposed to apply an overvoltage
threshold of 520V (RMS) and an over-current threshold of 400A (RMS). Which values are to be selected for
V_PTHRESHOLD and I_PTHRESHOLD?

Registers Controlling Time and RTC Functions
OP_TIME (0x1E)
This register holds the operating time expressed in 1/100 hours. The register will be reset to zero whenever the host writes
time or date to the RTC.
RTC_DATE (0x20)
This register holds the date information provided by the RTC. The register can be written to in order to set the date.
Bits 15-8: These bits contain the year information (0 to 255). The value 0 represents the year 2000.
Bits 23-16: These bits contain the month information (01 to 12). The value 01 represents January.
Bits 31-24: These bits contain the day of month information (01 to 31).
RTC_TIME_DAY (0x1F)
This register holds the time and day information provided by the RTC. The register can be written to in order to set the
time.
Bits 7-0: These bits contain the day of the week (01 to 07). The value 01 represents Sunday.
Bits 15-8: These bits contain the hour information (00 to 23). The value 00 represents midnight.
Bits 23-16: These bits contain the minutes information (00 to 59).
Bits 31-24: These bits contain the seconds information (00 to 59).
Example: The value 200835 is read from the OP_TIME register. This means that the meter has been running
since the last reset or power-up for
t = 800850/100h = 8008.50h or 8,008h and 30 minutes (333.6875 days or 333 days and 16.5h).
Registers Used for Test Functions
RTM (0x21)
This register controls the Real-Time Monitor. When the RTM_EN bit in the CONFIG register is set, the values of CE RAM
locations specified with the RTM register can be routed to the TMUX pin as a serial data stream. The TMUX bits in the
CONFIG register must be set to 3 in order to select the RTM output for the TMUX pin.
Bits 7-0: These bits (RTM3) select the CE address for RTM3.
