PRODUCTION DATA.
Whenever the device comes out of Power Off Mode or Shutdown Mode it goes through a power-on-reset (POR). Once the device internal power up sequence is completed the INT pin is asserted low without any of the bits in the interrupt status register (Reg 0x41) being set. Once the interrupt status register is read, the INT pin is released. When the device is coming out of shutdown mode of power off mode, none of the device functions will be available until the POR interrupt is asserted.
