STC15W104提供一個透過軟體Reset的方式，就是直接寫入IAP_CONTR暫存器的SWRST位元即可


main.s

    led .equ p3.2
 
    .org 0h
    jmp _start
     
    .org 100h
_start:
    setb led
    call delay_1s
    clr led
    call delay_1s
    mov 0c7h, #20h
    jmp $

    ; 1t + ((1t + (4t * 250) + 4t) * 200t) + 4t = 201005t
    ; 11.0592MHz = 0.09042us
    ; 201005t * 0.09042us = 18175us
