Reset Time
The SAM9G45 board design must comply with the power-up guidelines below to guarantee reli-
able operation of the device. Any deviation from these sequences may prevent the device from
booting.
Figure 46-2.
VDDCORE and VDDBU are controlled by internal POR (Power-On-Reset) to guarantee that
these power sources reach their target values prior to the release of POR.
