3. Instruction

(25) IA

Naming :

Increment Accumulator

Status :

Set

Format :

Ⅰ

Function :

A ← A+1

Data of the accumulator is incremented by one. Results are

returned to the accumulator.

A carry is not allowed to have effect upon the status.

(26) IY

Naming :

Increment Y-Register and Status 1 on Carry

Status :

Carry to status

Format :

Ⅰ

Function :

Y ← Y + 1

ST ← 1 (when Y = 15)

ST ← 0 (when Y < 15)

Data of the Y-register is incremented by one and results are

returned to the Y-register.

Carry data as results is transferred to the status. When the

total is more than 15, the status is set.

(27) DA

Naming :

Decrement Accumulator and Status 1 on Borrow

Status :

Carry to status

Format :

Ⅰ

Function :

A ← A - 1

ST ← 1(when A ≥1)

ST ← 0 (when A = 0)

Data of the accumulator is decremented by one. As a result

(by addition of Fh), if a borrow is caused, the status is reset to

″0″ by logic. If the data is more than one, no borrow occurs

and thus the status is set to ″1″.
