System Configuration
Although most features of the Freescale phyCORE-i.MX35 microcontroller are configured and/or pro-
grammed during the initialization routine, other features, which impact program execution, must be
configured prior to initialization via pin termination.
6.1 System Startup Configuration
During the reset cycle the i.MX35 processor reads the state of selected controller signals to determine
the basic system configuration. The configuration circuitries (pull-up or pull-down resistors) are
located on the phyCORE module. They are already set, so no further settings are necessary.
6.1.1 Power-Up-Mode
Note:
The i.MX35x controller has a defined power up sequence. Refer to the i.MX35 Data Sheet,
chapter 3.3 Power-Up sequence.
