(32) YNEA

Naming :

Y-Register Not Equal Accumulator

Status :

Comparison results to status

Format :

Function :

ó A

à 1 (when Y ó A)

à 0 (when Y = A)

Data of Y-register and accumulator are compared to check if

they are not equal.

Data of the Y-register and accumulator are logically compared.

Results are transferred to the status. Unless they are equal,

the status is set.

(33) YNEI

Naming :

Y-Register Not Equal Immediate

Status :

Comparison results to status

Format :

Operand :

Constant 0

õ i õ 15

Function :

ó i

à 1 (when Y ó i)

à 0 (when Y = i)

The constant of the Y-register is logically compared with 4bit

operand. Results are transferred to the status. Unless the

operand is equal to the constant, the status is set.

(34) KNEZ

Naming :

K Not Equal Zero

Status :

The status is set only when not equal

Format :

Function :

When K

ó 0, ST à 1

A test is made to check if K is not zero.

Data on K are compared with zero. Results are transferred to

the status. For input data not equal to zero, the status is set.

(35) RNEZ

Naming :

R Not Equal Zero

Status :

The status is set only when not equal

Format :

Function :

When R

ó 0, ST à 1

A test is made to check if R is not zero.

Data on R are compared with zero. Results are transferred to

the status. For input data not equal to zero, the status is set.
