Method and apparatus for coordinating program execution in a site controller with pattern execution in a tester

摘要

A method and apparatus for coordinating program execution in a site controller with pattern execution in a tester executes the pattern in the tester and a pattern interruption instruction. The pattern interruption instruction causes the tester to write to a service request register in the site controller specifying a value that specifies a requested subroutine and a data source. The site controller initiates execution of the requested subroutine in the site controller using the specified data source.
