Global Interrupt Enable:
This bit allows users to enable or disable the global interrupt gener-
ation for all channels within the T1 LIU Block. Once this global inter-
rupt is disabled, no interrupt will be generated to the Microprocessor
Interrupt Pin even when the individual “source” interrupt status bit
pulses ‘high’.
If this global interrupt is enabled, users still need to enable the indi-
vidual “source” interrupt in order for the T1 LIU Block to generate an
interrupt to the Microprocessor pin.
0 - Disables the global interrupt generation for all channels within
the T1 LIU Block.
1 - Enables the global interrupt generation for all channels within the
T1 LIU Block.

Software Reset
P Registers:
This bit allows users to reset the XRT86VL34 device. Writing a “1” to
this bit and keeping it at ’1’ for longer than 10s initiates a device
reset through the microprocessor interface. Once the XRT86VL34 is
reset, all internal circuits are placed in the reset state except the
microprocessor register bits.
0 = Disables software reset to the XRT86VL34 device.
1 = Enables software reset to the XRT86VL34 device.
