在KeyStone Architecture Serial RapidIO(SRIO) User Guide 2.3.9 Interrupt Operation
2.3.9.1 General Description INTDST16 - INTDST23: 有一句 No interrupt Pacing
请问,No interrupt Pacing 这里是什么意思?
如果中断映射到INTDST0 - INTDST15需要interrupt Pacing。意思是Interrupt pacing requires DSP core rewrite INTDSTn_RATE_CNT register after each interrupt service to enable the next interrupt。
如果用INTDST16 - INTDST23就不要考虑是否要写INTDSTn_RATE_CNT 寄存器的问题。
