Short Form of Emulated Instructions
The basic instruction set, together with the register implementations of the
program counter, stack pointer, status register, and constant generator, form
the emulated instruction set; these make up the popular instruction set. The
status bits are set according to the result of the execution of the basic
instruction that replaces the emulated instruction.
Table 5–18 describes these instructions.
