71M6515H Demo Board User’s Manual
Configuration Area (16):
This area labeled “Config” consists of several square buttons, entry fields and list fields located in a column
to the left of the Status/Mask area. Combinations of square buttons are mirrored as list fields. This means
the same function can be controlled by either pressing the square buttons or by selecting a setting from the
corresponding list field.

The equation to be used by the CE can be selected with the
three buttons as a binary word.
Entry field
SUM_CYCLES

buttons and
Entry field

(60)
The value for SUM_CYCLES can be selected with the six
buttons as a binary word. The length of an accumulation cycle
is
t = SUM_CYCLES * 16.66ms.
SUM_CYCLES should be > 15, unless VA = 0 or CE_ONLY =
1.
CKOUT_DSB
Square

ADC_DIS
Square
button
0
The ADC in the 6515H can be disabled by selecting “1” with
this button. This setting can be used for saving power on the
target chip.

The value for TMUX determines the source selected for the
TMUX output pin on the 71M6515H. The value can be
selected with the three buttons.
The phase to be used for measuring the signal frequency can
be selected with the two buttons as a binary word.
Entry field

The measured frequency of the phase determined by the
“Freq Source” field is displayed here.
CE_ONLY
Square
button
0
The CE only operation mode can be selected by setting this
square button to “1”. Omits internal calculation of IPHASE,
IRMS, VAH, and VRMS. This feature permits smaller
accumulation intervals (SUM_CYCLES < 15).

The CE mode to be used (standard or Rogowski) can be
selected with the two buttons as a binary word. IMAGE cannot
be selected while the CE is running. To change the setting,
follow this sequence:
1) Disable the CE.
2) Reset the 6515H.
3) Select the new image.
4) Enable the CE.
RESET
