Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: Set a value to the bit 2 of register K0, and execute the SNZ0 instruction to clear the EXF0 flag after executing at least one
instruction. According to the input state of G0/INT pin, the external interrupt request flag (EXF0) may be set when the
interrupt valid waveform is changed.

(5) Key-on wakeup control register K0
Key-on wakeup control register K0
The interrupt valid waveform for INT pin/key-on wakeup
valid waveform selection bit, the ports G1–G3 key-on
wakeup control bit and the ports S0–S3 key-on wakeup
control bit are assigned to the register K0. Set the contents
of this register through register A with the TK0A instruction.
The TAK0 instruction can be used to transfer the contents
of register K0 to register A.
