3.5.1. Entering Sleep Mode

Figure 10. Entering Sleep Mode Timing Diagram

The following sequence occurs when the device enters sleep mode:

  1. An internal or external request drives the sleep signal high, forcing the device to go into sleep mode.
  2. After a delay of T1, the power management controller powers down all the I/O buffers by de-asserting ioe signal that connects to oe and nsleep ports of the I/O buffers.
  3. After a delay of T2, the power management controller turns off all GCLK networks by disabling clk_ena[15:0] signal from LSB to MSB. After three clock cycles, the clk_ena[15:0] signal is fully disabled and transits into the sleep state.
  4. The power management controller remains in sleep state until the sleep signal is de-asserted.
  5. User logic will latch the running counter value before entering the sleep state and output to cnt_sleep_enter port. The running counter is then frozen.
  6. gpio_pad_output (GPIO) is tri-stated when ioe is de-asserted.
