3.5.2. Exiting Sleep Mode
Figure 11. Exiting Sleep Mode Timing Diagram
The following sequence occurs when the device exits sleep mode:
- An internal or external request drives the sleep signal low, forcing the device to exit sleep mode.
- 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.
- After a delay of T4, the power management controller powers up all the I/O buffers by asserting the ioe signal.
- The power management controller remains in awake state until the sleep signal is asserted.
- 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.
- gpio_pad_output (GPIO) is driving its output value when ioe is asserted.
