Preliminary Data Sheet
Initialization
The following describes the method by which initial chip settings are established when a system reset occurs.
Strapping
When the SysReset input is driven low (system reset), the state of certain I/O pins is read in order to enable default
initial conditions before PPC405EZ start-up. The actual instant of capture is the nearest system clock edge before
the deassertion of reset. These pins must be strapped using external pull-up (logical 1) or pull-down (logical 0)
resistors to select the desired default conditions. The recommended pull-up is 3k
Ω to +3.3V, or 10kΩ to +5V. The
recommended pull-down is 1K
Ω to GND. These pins are only used for strap functions during reset. They are used
for other signals during normal operation. The following table lists the strapping pins along with their functions and
strapping options. The signal names assigned to the pins for normal operation appear below the pin number.

Note: If reading of initialization data from
the IIC interface fails, the PPC405EZ
