(2) External interrupt control registers
Interrupt control register I1
Register I1 controls the valid waveform for the external 0 inter-
rupt. Set the contents of this register through register A with the
TI1A instruction. The TAI1 instruction can be used to transfer the
contents of register I1 to register A.

2: When the contents of I1

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

) 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.
