The JTAG minidriver interface allows the definition of alternate interface functions, instead of the built-in asynchronous driver module that is used by the standard JTAG interface drivers.

In addition to the functions defined in the minidriver.h file, the jtag_minidriver.h file must declare the following functions (or define static inline versions of them):

jtag_add_callback
jtag_add_callback4

The following core functions are declared in this file for use by the minidriver and do not need to be defined by an implementation:

default_interface_jtag_execute_queue()
