inlinestatic |
Determines if the hardware module(s) are currently synchronizing to the bus.
Checks to see if the underlying hardware peripheral module(s) are currently synchronizing across multiple clock domains to the hardware bus, This function can be used to delay further operations on a module until such time that it is ready, to prevent blocking delays for synchronization in the user application.
[in] | generator | Generic Clock Generator index to sync |
false | if the module has completed synchronization |
true | if the module synchronization is ongoing |
