(2) External interrupt control registers
Interrupt control register I1
Register I1 controls the valid waveform for the external 0 interrupt.
Set the contents of this register through register A with the TI1A in-
struction. The TAI1 instruction can be used to transfer the contents
of register I1 to register A.
Table 8 External interrupt control register
Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: When the contents of I12 and I13 are changed, the external interrupt request flag EXF0 may be set.
