Dynamic linking of codesets in universal remote control devices

A microcontroller, comprising:

• a processor;
• a read-only memory (ROM) that stores a first codeset and a second codeset, wherein the first codeset comprises a first keycode associated with a first key on a remote control device, and wherein the second codeset comprises a second keycode associated with a second key on the remote control device;
• a volatile memory that stores keycode link information;
• and
• a keycode link routine executable on the processor, execution of the keycode link routine storing the keycode link information, the keycode link information linking the second keycode in the second codeset to the first codeset.

A remote control device, comprising:

• a transmission circuit that transmits operational signals;
• a keypad comprising a plurality of keys;
• a processor;
• a read-only-memory (ROM) that stores a first codeset and a second codeset, wherein the first codeset comprises a first keycode associated with a first key on the remote control device, and wherein the second codeset comprises a second keycode associated with a second key on the remote control device;
• a volatile memory that stores keycode link information;
• and
• a keycode link routine executable on the processor, execution of the keycode link routine storing the keycode link information, the keycode link information linking the second keycode in the second codeset to the first codeset.

A device comprising:

• a read-only memory that stores a first codeset and a second codeset, wherein the first codeset comprises a first keycode, and wherein the second codeset comprises a second keycode;
• volatile memory that stores keycode link information, wherein the keycode link information links the second keycode in the second codeset to the first codeset, and wherein the keycode link information comprises a first identifier that identifies the second codeset and a second identifier that identifies the second keycode;
• and
• means for generating the keycode link information and writing the keycode link information into the volatile memory.
