The instruction associates the interrupt event number (EVNT) with the interrupt subroutine number (INT) and enables the interrupt event. The Interrupt Event Number (EVENT) is shown in the table below:

Interrupt number	Interrupt event
K0	X000 rising edge trigger
K1	X000 falling edge trigger
K2	X000 edge change trigger
K3	X001 rising edge trigger
K4	X001 falling edge trigger
K5	X001 edge change trigger
K6	Interrupt Timer 0 Note: Set value to D8173, timing range (1~32767ms) (resolution 1ms)
K7	Interrupt Timer 1 Note: Set value to D8174, timing range (1~32767ms) (resolution 1ms)
K8	X2 rising edge interruption
K9	X2 falling edge interruption
K10	X2 edge interrupt
K11	X3 rising edge interruption
K12	X3 falling edge interruption
K13	X3 edge interruption
K14	X4 rising edge interruption
K15	X4 falling edge interruption
K16	X4 edge interruption
K17	X5 rising edge interruption
K18	X5 falling edge interrupt
K19	X5 edge interrupt
K20	X6 rising edge interruption
K21	X6 falling edge interruption
K22	X6 edge interrupt
K23	X7 rising edge interruption
K24	X7 falling edge interruption
K25	X7 edge interrupt
