Reset and Configuration Strap Timing
This diagram illustrates the nRST pin timing requirements and its relation to the configuration strap
pins and output drive. Assertion of nRST is not a requirement. However, if used, it must be asserted
for the minimum period specified. Please refer to
information.
Note: Device configuration straps are latched as a result of nRST assertion. Refer to
nRST input assertion time
Configuration strap pins setup to nRST deassertion
Configuration strap pins hold after nRST deassertion
