(32) YNEA
Naming :
Y-Register Not Equal Accumulator
Comparison results to status
Status :
Format :
Function :
Y
A
ST
ST
1 (when Y A)
0 (when Y = A)
<Purpose>
Data of Y-register and accumulator are compared to check if
they are not equal.
<Comment>
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 :
Status :
Y-Register Not Equal Immediate
Comparison results to status
Format :

Function :
Constant 0

Y
i
ST
ST
1 (when Y i)
0 (when Y = i)
<Comment>
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 :
Status :
K Not Equal Zero
The status is set only when not equal
Format :
Function :
<Purpose>
<Comment>
When K 0, ST
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.

Function :
<Purpose>
<Comment>
When R 0, ST
A test is made to check if R is not zero.
Data on R are compared with zero. Results are transferred to
