MACHINE INSTRUCTIONS (INDEX BY ALPHABET) (continued)
SNZ0 (Skip if Non Zero condition of external 0 interrupt request flag)
0000111000
038
11
–
V10 = 0: (EXF0) = 1
Grouping:
Interrupt operation
Description: When V10 = 0 : Clears (0) to the EXF0 flag
and skips the next instruction when external
0 interrupt request flag EXF0 is “1.” When
the EXF0 flag is “0,” executes the next in-
struction.
When V10 = 1 : This instruction is equiva-
lent to the NOP instruction.
Operation:
V10 = 0: (EXF0) = 1 ?
(EXF0) ← 0
V10 = 1: SNZ0 = NOP
(V10 : bit 0 of the interrupt control register V1)
SEA n (Skip Equal, Accumulator with immediate data n)
0000100101
025
22
–
(A) = n
Grouping:
Comparison operation
Description: Skips the next instruction when the con-
tents of register A is equal to the value n in
the immediate field.
Executes the next instruction when the con-
tents of register A is not equal to the value n
in the immediate field.
Operation:
(A) = n ?
n = 0 to 15
SEAM (Skip Equal, Accumulator with Memory)
0000100110

11
–
(A) = (M(DP))
Grouping:
Comparison operation
Description: Skips the next instruction when the con-
tents of register A is equal to the contents of
M(DP).
Executes the next instruction when the con-
tents of register A is not equal to the
contents of M(DP).
Operation:
(A) = (M(DP)) ?
SD (Set port D specified by register Y)
0000010101
015
11
–
Grouping:
Input/Output operation
Description: Sets (1) to a bit of port D specified by register Y.
Note:
(Y) = 0 to 5.
Do not execute this instruction if values ex-
cept above are set to register Y.
Operation:
(D(Y)) ← 1
(Y) = 0 to 5
