Bit 2—Zero (Z): This bit is set to “1” to indicate a zero result and cleared to “0” to indicate a
nonzero result.
Bit 1—Overflow (V): This bit is set to “1” when an arithmetic overflow occurs, and cleared to
“0” at other times.
Bit 0—Carry (C): This bit is used by:
• Add and subtract instructions, to indicate a carry or borrow at the most significant bit of the
• Shift and rotate instructions, to store the value shifted out of the most significant or least
• Bit manipulation and bit load instructions, as a bit accumulator
The LDC, STC, ANDC, ORC, and XORC instructions enable the CPU to load and store the CCR,
and to set or clear selected bits by logic operations.
Some instructions leave some or all of the flag bits unchanged. The action of each instruction on
the flag bits is shown in Appendix A.1, “Instruction Set List.” See the H8/300 Series
Programming Manual for further details.
3.2.3 Initial Register Values
When the CPU is reset, the program counter (PC) is loaded from the vector table and the interrupt
mask bit (I) in the CCR is set to “1.” The other CCR bits and the general registers are not
initialized.
In particular, the stack pointer (R7) is not initialized. To prevent program crashes the stack pointer
should be initialized by software, by the first instruction executed after a reset.
