MB89640 Series
The RP indicates 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 illustrated below.
The CCR consists of bits indicating the results of arithmetic operations and the contents of transfer data and
bits for control of CPU operations at the time of an interrupt.
H-flag:
Set when a carry or a borrow from bit 3 to bit 4 occurs as a result of an arithmetic operation. Cleared
otherwise. This flag is for decimal adjustment instructions.
I-flag:
Interrupt is allowed when this flag is set to 1. Interrupt is prohibited when the flag is set to 0. Set to 0
when reset.
IL1, 0:
Indicates the level of the interrupt currently allowed. Processes an interrupt only if its request level is
higher than the value indicated by this bit.
N-flag:
Set if the MSB is set to 1 as the result of an arithmetic operation. Cleared when the bit is set to 0.
Z-flag:
Set when an arithmetic operation results in 0. Cleared otherwise.
V-flag:
Set if the complement on 2 overflows as a result of an arithmetic operation. Reset if the overflow does
not occur.
C-flag:
Set when a carry or a borrow from bit 7 occurs as a result of an arithmetic operation. Cleared otherwise.
Set to the shift-out value in the case of a shift instruction.
