TC configuration structure.
Configuration struct for a TC instance. This structure should be initialized by the tc_get_config_defaults function before being modified by the user application.

Set to true
to enable double buffering write.
When enabled any write through tc_set_top_value(), tc_set_compare_value() and will direct to the buffer register as buffered value, and the buffered value will be committed to effective register on UPDATE condition, if update is not locked.
