Sleep Mode Timing
Sleep mode is internally asserted, and it asserts the nRESET_OUT and PWR_EN signals.
Figure 6-5 and Table 6-6 show the required timing parameters for sleep mode.
Note: When bit SL_ROD is set in the Power Manager Sleep Configuration register, nRESET_OUT, is
not asserted during GPIO reset. See the “Clocks and Power Manager” chapter in the Intel
PXA27x Processor Family Developer’s Manual for register details.

NOTES:
1. GPIO<1> is not recognized as a reset source again until configured to do so in software. Software must
check the state of GPIO<1> before configuring as a reset to ensure that no spurious reset is generated. For
details, see the “Clocks and Power Manager” chapter in the Intel PXA27x Processor Family Developer’s
Manual.
2. Time is 512*N processor clock cycles plus up to 4 cycles of the 13.000-MHz input clock.
3. Time during the frequency-change sequence depends on the state of the PLL lock detector at the assertion
of GPIO reset. The lock detector has a maximum time of 350 s plus synchronization.
4. In standby, sleep, and deep-sleep modes, this time is in addition to the wake-up time from the low-power
mode.
5. The tCS0 specification is also applicable to Power-On reset, Hardware reset, Watchdog reset and Deep-
Sleep/Sleep mode exit.
