使用APB4; APB4适用于以AHB5,AXI为基础的Bus系统中,因为他们都支持secure/non-secure的访问,而且AXI是支持write strobe的,所以这种情况下使用APB4是比较合适的...支持AXI协议的话,外设选择APB4更合适 Cortex-M23和Cortex-M33使用AHB5协议,可以支持secure/non-secure,外设选择APB4更合适 !!!如果系统不支持 AMBA...
PENABLE Master This strobe signal is used to time all accesses on the peripheral bus. The enable signal is used to indicate the second cycle of an APB transfer. The rising edge of PENABLE occurs in the middle of the APB transfer. PWRITE Master When HIGH this signal indicates an APB write...

处理器来说,Cortex-A/R系列处理器有使用AXI,ACE,和CHI协议,支持secure/non-secure访问和Write Strobe,因此在一个基于Cortex-A/R处理器的SoC系统中,APB的slave使用APB4;Cortex-M处理器Cortex-M0/M0+/M3/M4使用AHB-lite协议,因此外设使用APB3更合适Cortex-M7可以选择支持AXI协议,如果是 ...
