Notes: 1. The number of states in cases where the instruction code and its operands are located
in on-chip memory is shown here. For other cases see section A.3, Number of
Execution States.
Execution States.
2. n is the value set in register R4L or R4.
(1) Set to 1 when a carry or borrow occurs at bit 11; otherwise cleared to 0.
(2) Set to 1 when a carry or borrow occurs at bit 27; otherwise cleared to 0.
(3) Retains its previous value when the result is zero; otherwise cleared to 0.
(4) Set to 1 when the adjustment produces a carry; otherwise retains its previous value.
(5) The number of states required for execution of an instruction that transfers data in
synchronization with the E clock is variable.
(6) Set to 1 when the divisor is negative; otherwise cleared to 0.
(7) Set to 1 when the divisor is zero; otherwise cleared to 0.
(8) Set to 1 when the quotient is negative; otherwise cleared to 0.
