3.5.2. Exiting Sleep Mode

Figure 11. Exiting Sleep Mode Timing Diagram

The following sequence occurs when the device exits sleep mode:

  1. An internal or external request drives the sleep signal low, forcing the device to exit sleep mode.
  2. After a delay of T3, the power management controller turns on all GCLK networks by enabling clk_ena[15:0] signal from LSB to MSB. After three clock cycles, the clk_ena[15:0] signal is fully enabled and all GCLK networks are turned on.
  3. After a delay of T4, the power management controller powers up all the I/O buffers by asserting the ioe signal.
  4. The power management controller remains in awake state until the sleep signal is asserted.
  5. User logic will latch the running counter value before the awake state and output to cnt_sleep_exit port. The running counter is then release from freeze.
  6. gpio_pad_output (GPIO) is driving its output value when ioe is asserted.
