–
(A) = n
Grouping:
Comparison operation
Description: Skips the next instruction when the contents
of register A is equal to the value n in the im-
mediate 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

–
(A) = (M(DP))
Grouping:
Comparison operation
Description: Skips the next instruction when the contents
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)) ?

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 : Skips the next instruction
when external 0 interrupt request flag EXF0
is “1.” After skipping, clears (0) to the EXF0
flag. When the EXF0 flag is “0,” executes the
next instruction.
When V10 = 1 : This instruction is equivalent
to the NOP instruction.
Operation:
V10 = 0: (EXF0) = 1 ?
After skipping, (EXF0)
← 0
V10 = 1: SNZ0 = NOP
(V10 : bit 0 of the interrupt control register V1)
SNZAD (Skip if Non Zero condition of A/D conversion completion flag)

–
V22 = 0: (ADF) = 1
Grouping:
A/D conversion operation
Description: When V22 = 0 : Skips the next instruction
when A/D conversion completion flag ADF
is “1.” After skipping, clears (0) to the ADF
flag. When the ADF flag is “0,” executes the
next instruction.
When V22 = 1 : This instruction is equivalent
to the NOP instruction.
Operation:
V22 = 0: (ADF) = 1 ?
After skipping, (ADF)
← 0
V22 = 1: SNZAD = NOP
(V22 : bit 2 of the interrupt control register V2)
