4.3.1 Inherent
MC68HC705J2
Inherent instructions are those that have no operand, such as return from
interrupt (RTI) and stop (STOP). Other inherent instructions are those that act
on data in the CPU registers, such as set carry flag (SEC) and increment
accumulator (INCA). Inherent instructions require no memory address and are
one byte long. Table 4-1 lists the instructions that use the inherent addressing
mode.
