G1/TOUT pin function selection bit

Prescaler/timer 1 operation start bit

Timer 1 interrupt enable bit

External interrupt enable bit

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 to “0” after executing at least

one instruction. According to the input state of G0/INT pin, the external interrupt request flag (EXF0) may be set to “1” when

the interrupt valid waveform is changed.
