Initialization
The following describes the method by which initial chip settings are established when a system reset occurs.
Pin Strapping
While the SysReset input pin is low (system reset), the state of certain I/O pins is read to enable default initial
conditions prior to NPe405L start-up. The actual capture instant is the nearest reference 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. These pins are use for strap functions only 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.
