This button, in conjunction with PULSE_FAST and WRATE (in
the Pulse Source area), selects the X factor for the pulse
generation rate.

Additional ADC gain of 8x can be selected for phase A by
selecting “1”.
Additional ADC gain of 8x can be selected for phase B by
selecting “1”.
Additional ADC gain of 8x can be selected for phase C by
selecting “1”.
This button enables temperature compensation by the host. If
the bit associated with DEFAULT PPM is 0, the 71M6515H
internally controls the temperature compensation based on the
stored VREF characterization values. When DEFAULT PPM is
0, the host may write values into the PPMC and PPMC2 fields
to influence temperature compensation.
When DEFAULT PPM is toggled back to 0 after the host had
written values to the PPMC and PPMC2 fields, these fields will
go back to displaying the original internal values.
Status Word and Status Mask Area (17):
This area consists of 18 square buttons and indicator lights towards the right edge of the GUI window.
The bits of the STATUS word are displayed in the indicator lights right next to the square buttons. A green
light indicates no activity, a red light indicates that the corresponding bit is set.
Individual bits of the STATUS word can be made to generate interrupts. When the square button right next to
the status bit is pressed (1), the corresponding bit, when active, will generate an interrupt on the IRQZ
output pin. Activity on the IRQZ output pin is indicated with the green LED D8 on the Demo Board.
