1. A method of coordinating program execution in a site controller with test pattern execution in a tester comprising the steps of:
- executing a test pattern in the tester, executing a pattern interruption instruction in the tester, the tester writing to a service request register in the site controller specifying a requested subroutine and a data source, the site controller initiating execution of said requested subroutine in the site controller in response to a value in said service request register.

Abstract
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.

14. An apparatus for coordinating program execution comprising
a site controller executing a routine, a tester executing a test pattern, a bus interconnecting said site controller and said tester, a trigger register in said tester that initiates execution of said test pattern upon a write to said trigger register by said site controller, and at least one service request register in said site controller having a value written by said tester that initiates and indicates to said site controller a requested subroutine for execution in said site controller.
