Pin Prototyping Headers - Arrow BeMicro CV A9 Hardware Reference Manual

Note 1: I/O voltage for this interface is selectable using the VCCIO_SEL jumper

40 Pin Prototyping Headers

The BeMicro CV A9 board includes two 2×20 prototyping headers. The FPGA user I/O pins are
routed directly to the headers for design testing, debugging, verification and prototyping.
