Notes 1:
“
R
”
represents read enabled, and
“
W
”
represents write enabled.
2: These instructions are equivalent to the NOP instruction.
3: When the contents of I1
2
and I1
3
are changed, the external interrupt request flag EXF0 may be set. Accordingly, clear EXF0 flag with the SNZ0 in-
struction when the bit 0 (V1
0
) of register V1 to
“
0
”
. In this time, set the NOP instruction after the SNZ0 instruction, for the case when a skip is
performed with the SNZ0 instruction.
