4.7 Interrupt4.7.1 OutlineMSM80C154S/MSM83C154S is equipped with six interrupts.1. INT0 External interrupt 02. TM0 Timer interrupt 03. INT1 External interrupt 14. TM1 Timer interrupt 15. SI/O Serial port interrupt6. TM2 Timer interrupt 2These six interrupts are controlled by interrupt enable register (IE) and interrupt priorityregister (IP). When the relevant interrupt conditions are met, the respective interrupt addressis called and the interrupt routine is commenced.The interrupt addresses are listed in Table 4-18, and the interrupt control equivalent circuitis shown in Figure 4-44.Table 4-18 lnterrupt addresses123456Interrupt sourceExternal interruput 0Timer interruput 0External interruput 1Timer interruput 1Serial port interruputTimer interruput 2Interruput address3[0003hH]11[000BhH]19[0013hH]27[001BhH]35[0023hH]43[002BhH]
