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
