The PS register can further be divided into the register bank pointer in the higher 8 bits (RP) and the condition code
register in the lower 8 bits (CCR) . (See the diagram below.)
The RP points to the address of the register bank currently in use. The relationship between the pointer contents
and the actual address is based on the conversion rule shown next.
The CCR consists of the bits indicating arithmetic operation results or transfer data contents and the bits that
control CPU operations at the time of an interrupt.
H flag
: The flag is set to “1” when an arithmetic operation results in a carry from bit 3 to bit 4 or in a borrow
from bit 4 to bit 3. The bit is cleared to “0” in other instances. The flag is for decimal adjustment
instructions; do not use for other than additions and subtractions.
: Interrupt is enabled when this flag is set to “1.” Interrupt is disabled when this flag is set to “0.” The
flag is set to “0” when reset.
: Indicates the level of the interrupt currently enabled. An interrupt is processed only if its level is
higher than the value this bit indicates.
