Sleep Mode Timing
Sleep mode is asserted internally; and asserts the nRESET_OUT and PWR_EN signals. The
sequence indicated in
Figure 6, “Sleep Mode Timing” on page 34
and detailed in
Figure 18, “Sleep
Mode Timing Specifications” on page 34
is the required timing parameters for sleep mode.

NOTES:
1. GP[1] is not recognized as a reset source again until configured to do so in software. Software should
check the state of GP[1] before configuring as a reset to ensure no spurious reset is generated.
2. Time is 512*N processor clock cycles plus up to 4 cycles of the 3.6864-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 350μs plus synchronization.

Note:
nBATT_FAULT and nVDD_FAULT must be high before nRESET is
deasserted or the application processor will enter Sleep Mode
