Section 1 CPU
Some instructions leave some or all of the flag bits unchanged. For the action of each instruction
on the flag bits, refer to the detailed descriptions of the instructions starting in section 2.2.1.
Operations can be performed on the CCR bits by the LDC, STC, ANDC, ORC, and XORC
instructions. The N, Z, V, and C flags are used as branching conditions for conditional branch
(Bcc) instructions.
(4) Multiply-Accumulate Register (MAC)
The MAC register is supported only by the H8S/2600 CPU. This 64-bit register stores the results
of multiply-and-accumulate operations. It consists of two 32-bit registers denoted MACH and
MACL. The lower 10 bits of MACH are valid; the upper bits are a sign extension.
1.4.4
Initial Register Values
Reset exception handling loads the CPU’s program counter (PC) from the vector table, clears the
trace bit in EXR to 0, and sets the interrupt mask bits in CCR and EXR to 1. The other CCR bits
and the general registers are not initialized. In particular, the stack pointer (ER7) is not initialized.
The stack pointer should therefore be initialized by an MOV.L instruction executed immediately
after a reset.
