下面这句话中,say这一句翻译为什么?
When the PC jumps to IRQ_Handler (after executing the instruction at 0x18), the return
address from this ISR is already stored in LR_irq. Say this is pushed into the stack
(SP_irq). Now when foo() is called, the LR_irq get overwritten with the address of the
instruction following foo().

当电脑跳跃到IRQ_Handler (后执行指令0x18 ) ,返回
从这个地址ISR公司已经在LR_irq储存。说这是推入堆栈
( SP_irq ) 。现在,当foo ( )从所谓的LR_irq获得覆盖的地址
以下foo的指示( ) 。
