AMBA APB Signal Descriptions<br />

Signal Name Direction Description<br />

PCLK I AMBA APB clock, used to time all bus transfers<br />

PRSTn I AMBA APB reset signal, active LOW<br />

psel I GPIO select signal from the APB bus. When set to 1, this signal indicates that the slave<br />

device is selected by the AMBA APB bridge, and that a data transfer is required.<br />

penable I AMBA APB enable signal<br />

pwrite I AMBA APB transfer direction signal. It indicates a write access when HIGH, and a read<br />

access when LOW.<br />

paddr I AMBA APB address bus<br />

pwdata I AMBA APB write data bus<br />

prdata O AMBA APB read data bus
