4.4.1
POR_B is normally connected to a power management integrated circuit (PMIC). The PMIC asserts
POR_B while the power supplies are turned on and negates POR_B after the power up sequence is
finished. See
Assuming the i.MX35 chip is already fully powered; it is still possible to reset all of the modules to their
default reset by asserting POR_B for at least 4 CKIL cycles and later de-asserting POR_B. This method
of resetting the i.MX35 can also be supported by tying the POR_B and RESET_IN_B pins together.
4.4.2
System reset can be achieved by asserting RESET_IN_B for at least 4 CKIL cycles and later negating
RESET_IN_B. The following modules are not reset upon system reset: RTC, PLLs, CCM, and IIM.
POR_B pin must be deasserted all the time.

and temperature conditions. These values are derived from the i.MX35 with core clock speeds up to
