• Rule for Conversion of Actual Addresses in the General-purpose Register Area
The RP indicates the address of the register bank currently being used. The relationship between the content
of RP and the real address conforms to the conversion rule illustrated below:
The DP specifies the area for mapping instructions (16 different instructions such as MOV A, dir) using direct
addresses to 0080
The CCR consists of the bits indicating arithmetic operation results or transfer data contents and the bits that
control CPU operations at interrupt.

: Set to “1” when a carry or a borrow from bit 3 to bit 4 occurs as a result of an arithmetic operation.
: Interrupt is enabled when this flag is set to “1”. Interrupt is disabled when this flag is set to “0”.
Set to “1” if the MSB is set to “1” as the result of an arithmetic operation. Cleared to “0” when the
bit is set to “0”.
Set to “1” when an arithmetic operation results in “0”. Cleared to “0” otherwise.
Set to “1” if the complement on 2 overflows as a result of an arithmetic operation. Cleared to “0”
otherwise.
Set to “1” when a carry or a borrow from bit 7 occurs as a result of an arithmetic operation. Cleared
to “0” otherwise. Set to the shift-out value in the case of a shift instruction.
Cleared to “0” otherwise. This flag is for decimal adjustment instructions.
The flag is set to “0” when reset.
