stm8 iar中,为什么进入中断,就修改一次中断级别
132 INTERRUPT_HANDLER(EXTI_PORTC_IRQHandler, 5)
133 {
\ EXTI_PORTC_IRQHandler:
\ _interrupt_7:
\ 000000 8A PUSH CC
\ 000001 84 POP A
\ 000002 A4BF AND A, #0xbf
\ 000004 88 PUSH A
\ 000005 86 POP CC
\ 000006 8D000000 CALLF L:?push_l0
\ 00000A 8D000000 CALLF L:?push_l1
中断函数是
INTERRUPT_HANDLER(EXTI_PORTC_IRQHandler, 5)
{
u32 ii= add(323,424);}
没有设置优先级呀 |
