- TO PD Z DC C
This register contains the arithmetic status of the ALU, and the RESET status. And the reset status bits TO and PD ,
are not writable.
C : Carry/borrow bit.
ADDAR, ADDIA
= 1, Carry occurred.
= 0, No Carry occurred.
SUBAR, SUBIA
= 1, No borrow occurred.
= 0, Borrow occurred.
Note : A subtraction is executed by adding the two’s complement of the second operand. For rotate (RRR, RLR)
instructions, this bit is loaded with either the high or low order bit of the source register.
DC : Half carry/half borrow bit
ADDAR, ADDIA
= 1, Carry from the 4th low order bit of the result occurred.
= 0, No Carry from the 4th low order bit of the result occurred.
SUBAR, SUBIA
= 1, No Borrow from the 4th low order bit of the result occurred.
= 0, Borrow from the 4th low order bit of the result occurred.
Z : Zero bit.
= 1, The result of a logic operation is zero.
= 0, The result of a logic operation is not zero.
