- *
- * In addtion to the functions defined in the c minidriver.h file, the

- * define static inline versions of them):
- * - jtag_add_callback
- * - jtag_add_callback4
- * - interface_jtag_add_dr_out
- *
- * The following core functions are declared in this file for use by
- * the minidriver and do @b not need to be defined by an implementation:
- * - default_interface_jtag_execute_queue()
