Power-On Configuration Strap Valid Timing
This diagram illustrates the configuration strap valid timing requirements in relation to power-on. In
order for valid configuration strap values to be read at power-on, the following timing requirements
must be met.
Note: Configuration straps must only be pulled high or low. Configuration straps must not be driven
Note: Device configuration straps are also latched as a result of nRST assertion. Refer to
VDD33IO
Configuration strap valid time
as inputs.
