A range of 16-bit instructions treat the A and B registers as a combined 16-bit D register for comparison (X and Y registers may also be compared to 16-bit memory operands), addition, subtraction and shift operations, or can add the B accumulator to the X or Y index registers.

The most common version has five ports, A, B, C, D, and E, but some have as few as 3 ports (version D3). Each port is eight bits wide except for D, which is six bits (in some variations of the chip, D also has eight bits).

It can be stored in on-chip ROM, EPROM, or external memory (also typically EPROM). BUFFALO is available for most 68HC11 family derivatives as it generally only depends upon having access to a single UART (SCI, or Serial Communications Interface, in Motorola parlance). BUFFALO can also run on devices that do not have internal non-volatile memory, such as the 68HC11A0, A1, E0, E1, and F1 derivatives. </p> <div class="mw-heading mw-heading2"><h2 id="Other_versions">Other versions</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Motorola_68HC11&amp;action=edit&amp;section=3" title="Edit section: Other versions"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/Freescale_68HC16" class="mw-redirect" title="Freescale 68HC16">Freescale 68HC16</a> microcontroller family is intended as a <a href="/wiki/16-bit" class="mw-redirect" title="16-bit">16-bit</a> mostly software-compatible upgrade of the 68HC11. </p><p>The <a href="/wiki/Freescale_68HC12" class="mw-redirect" title="Freescale 68HC12">Freescale 68HC12</a> microcontroller family is an enhanced 16-bit version of the 68HC11. </p><p>The <a href="/wiki/Handy_Board" title="Handy Board">Handy Board</a> robotics controller by Fred Martin is based on the 68HC11.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">&#91;</span>6<span class="cite-bracket">&#93;</span></a></sup> </p><p>A MC68HC24 port replacement unit is available for the 68HC11D, which lacks ports B and C.
