/*---------------------------------------------------------
 * 16bit-instructions.h
 *
 * This .h file contains the definitions for the 16-bit core 
 * instructions (the 16bit core of the 18cxxx processors that
 * is). Most of the instructions are derived from the corresponding
 * 12 and 14 bit core instructions. However, the virtual function
 * 'execute' is replaced. This is because the memory addressing and
 * the status register are  different for the 16bit core. The alternative is
 * is to patch the existing instructions with the 16bit stuff.
 * I feel that this is an unwarranted performance hit. So gpsim
 * is slightly bigger, but it's also slightly faster...
