PRELIMINARY INFORMATION AUG 02, 2011
Figure 5.4.2.1-1 Power-On-Reset timing diagram
The power on reset is designed to cause a reset during the power on cycle of the chip. The reset will be
deactivated when the supply crosses Vpor.
After the power up sequence the power on reset block will only cause a new reset if the power supply voltage
drops below VDDmin and the rise and fall times of the supply are below the specified values.
