Program Control

Several hardware and software mechanisms provide program control:

- Program control logic decodes instructions, manages the 4-level pipeline,

stores the status of operations, and decodes conditional operations. Hard-

ware elements included in the program control logic are the program

counter, the status registers, the stack, and the address-generation logic.

- Software mechanisms used for program control include branches, calls,

conditional instructions, a repeat instruction, reset, interrupts, and power-

down modes.

Table 2–1 shows where you can find detailed information about these program

control features.

Serial-Scan Emulation

The ’C24x has seven pins dedicated to the serial scan emulation port (JTAG

port). This port allows for non-intrusive emulation of ’C24x devices, and is sup-

ported by Texas Instruments emulation tools and by many third party debugger

tools. For documentation on these emulation and debugger tools, see

Documentation From Texas Instruments in the preface section of this book,

and

Design Considerations for Using XDS510 Emulator in Appendix C.
