Section 1 CPU
The memory indirect addressing mode (@@aa:8) employed in the JMP and JSR instructions uses
an 8-bit absolute address to specify a memory operand that contains a branch address. In normal
mode the operand is a 16-bit word operand, providing a 16-bit branch address. Branch addresses
can be stored in the top area from H'0000 to H'00FF. Note that this area is also used for the
exception vector table.
Stack Structure: When the program counter (PC) is pushed on the stack in a subroutine call, and
the PC and condition-code register (CCR) are pushed on the stack in exception handling, they are
stored in the same way as in the H8/300 CPU. See figure 1.3.
