The JTAG interface can be implemented with a software or hardware fifo.
TAP_DRSHIFT and TAP_IRSHIFT are illegal end states; however, TAP_DRSHIFT/IRSHIFT can be emulated as end states, by using longer scans.
Code that is relatively insensitive to the path taken through state machine (as long as it is JTAG compliant) can use endstate for jtag_add_xxx_scan(). Otherwise, the pause state must be specified as end state and a subsequent jtag_add_pathmove() must be issued.

typedef int(* jtag_callback_t) (jtag_callback_data_t data0, jtag_callback_data_t data1, jtag_callback_data_t data2, jtag_callback_data_t data3) |
Defines the interface of the JTAG callback mechanism.
Such callbacks can be executed once the queue has been flushed.
The JTAG queue can be executed synchronously or asynchronously. Typically for USB, the queue is executed asynchronously. For low-latency interfaces, the queue may be executed synchronously.
The callback mechanism is very general and does not make many assumptions about what the callback does or what its arguments are. These callbacks are typically executed after the entire JTAG queue has been executed for e.g. USB interfaces, and they are guaranteed to be invoked in the order that they were queued.
If the execution of the queue fails before the callbacks, then – depending on driver implementation – the callbacks may or may not be invoked.
data0 | Typically used to point to the data to operate on. Frequently this will be the data clocked in during a shift operation. |
data1 | An integer big enough to use as an int or a pointer. |
data2 | An integer big enough to use as an int or a pointer. |
data3 | An integer big enough to use as an int or a pointer. |

void jtag_add_pathmove | ( | int | num_states, |
const tap_state_t * | path | ||
) |
Application code must assume that interfaces will implement transitions between states with different paths and path lengths through the state diagram.
The path will vary across interface and also across versions of the same interface over time. Even if the OpenOCD code is unchanged, the actual path taken may vary over time and versions of interface firmware or PCB revisions.
Use jtag_add_pathmove() when specific transition sequences are required.
Do not use jtag_add_pathmove() unless you need to, but do use it if you have to.
DANGER! If the target is dependent upon a particular sequence of transitions for things to work correctly(e.g. as a workaround for an errata that contradicts the JTAG standard), then pathmove must be used, even if some jtag interfaces happen to use the desired path. Worse, the jtag interface used for testing a particular implementation, could happen to use the "desired" path when transitioning to/from end state.
A list of unambiguous single clock state transitions, not all drivers can support this, but it is required for e.g. XScale and Xilinx support
Note! TAP_RESET must not be used in the path!
Note that the first on the list must be reachable via a single transition from the current state.
All drivers are required to implement jtag_add_pathmove(). However, if the pathmove sequence can not be precisely executed, an interface_jtag_add_pathmove() or jtag_execute_queue() must return an error. It is legal, but not recommended, that a driver returns an error in all cases for a pathmove if it can only implement a few transitions and therefore a partial implementation of pathmove would have little practical application.
If an error occurs, jtag_error will contain one of these error codes:

void jtag_add_reset | ( | int | req_tlr_or_trst, |

A reset of the TAP state machine can be requested.
Whether tms or trst reset is used depends on the capabilities of the target and jtag interface(reset_config command configures this).
srst can driver a reset of the TAP state machine and vice versa
Application code may need to examine value of jtag_reset_config to determine the proper codepath
DANGER! Even though srst drives trst, trst might not be connected to the interface, and it might actually be harmful to assert trst in this case.
This is why combinations such as "reset_config srst_only srst_pulls_trst" are supported.
only req_tlr_or_trst and srst can have a transition for a call as the effects of transitioning both at the "same time" are undefined, but when srst_pulls_trst or vice versa, then trst & srst must be asserted together.

int jtag_execute_queue | ( | void | ) |
For software FIFO implementations, the queued commands can be executed during this call or earlier.
A sw queue might decide to push out some of the jtag_add_xxx() operations once the queue is "big enough".
This fn will return an error code if any of the prior jtag_add_xxx() calls caused a failure, e.g. check failure. Note that it does not matter if the operation was executed before jtag_execute_queue(), jtag_execute_queue() will still return an error code.
All jtag_add_xxx() calls that have in_handler != NULL will have been executed when this fn returns, but if what has been queued only clocks data out, without reading anything back, then JTAG could be running after jtag_execute_queue() returns. The API does not define a way to flush a hw FIFO that runs after jtag_execute_queue() returns.
jtag_add_xxx() commands can either be executed immediately or at some time between the jtag_add_xxx() fn call and jtag_execute_queue().
