I2C register 0x07 is Read Only. The register values get latched whenever a system-level interrupt occurs (IRQ goes high); and, the
register values are cleared when the IRQ gets cleared upon reading register 0x01. This I2C register can be used for debug purposes, if
needed. If register 0x01 is not read, then the latched values in register x07, will keep on updating based on any system level event.
