The collection of four mandatory and one optional terminals that form the input/output
and control interface to a JTAG boundary-scan architecture. The mandatory terminals
are TDI, TDO, TMS, and TCK. The optional terminal is nTRST.
A halfword which specifies an operation for an ARM processor in Thumb state to
perform. Thumb instructions must be halfword-aligned.
A processor that is executing Thumb (16-bit) instructions is operating in Thumb state.
See Undefined.
Indicates an instruction that generates an undefined instruction trap.
See Unpredictable
Means the result of an instruction cannot be relied upon. Unpredictable instructions
must not halt or hang the processor, or any parts of the system.
Do not contain valid data, and a value can vary from moment to moment, instruction to
instruction, and implementation to implementation.
A location in the image that is monitored. If the value stored there changes, the debugger
halts execution of the image.
