Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: Depending on the input state of D5/INT pin, the external interrupt request flag EXF0 may be set to “1” when the contents of
I12 is changed. Accordingly, set a value to bit 2 of register I1 and execute the SNZ0 instruction to clear the EXF0 flag after
executing at least one instruction.
