For new developers unfamiliar with the technology, @ref primerjtag provides
a brief introduction to the IEEE JTAG interface.
-The OpenOCD JTAG library API covers several functional areas:

+The OpenOCD JTAG library API covers several functional areas. The jtag
+@b core communicates through the @b minidriver API with either its full
+@a driver implementation (src/jtag/jtag_driver.c) or a @a minidriver .
+Internally, the @b command API is used by the JTAG driver for managing
+asynchronous transactions.
+
+- @subpage jtagcore
+ - @b public API routines
+ - declared in @c src/jtag/jtag.h
+ - used by other modules
+
+- @subpage jtagcmd
+ - @b private command queue API
+ - declared in @c src/jtag/commands.h
+ - provides routines used internally by the full JTAG drivers.
+
+- @subpage jtagiface
+ - @b private interface driver API
+ - declared in @c src/jtag/interface.h
+ - used by the core, minidrivers, and the full interface device drivers.
+ - allows implementing new interface device drivers.
+ - includes the Cable/TAP API (commands starting with @c tap_)
+
+- @subpage jtagdriver
+ - @b private minidriver API
+ - declared in @c src/jtag/minidriver.h
+ - used @a only by the core and minidriver implementations:
+ - @c jtag_driver.c (in-tree OpenOCD drivers)
+ - @c zy1000/build/include/jtag_minidriver.h (ZY1000 minidriver)
+ - future implementations (on other embedded hosts)
+ - interface device drivers do @b not need this API.
