4 XSYS Connector
XTAG-2 Hardware Manual (1.0)
The XTAG-2 includes an XSYS 20-way IDC header, which can be used to connect it to
an XMOS development board for debugging programs on the hardware.
The XSYS connector provides pins for JTAG control, system reset, processor debug, a
duplex UART link and a 2-bit serial XMOS Link.
The routing of these I/O pins along with the power pins is shown on the following
page.
