XK-1 Hardware Manual (1.2.2)
The XTAG-2 converts between XSYS and USB 2.0, allowing the XK-1 to be connected
XS1-L1 can then be put into JTAG mode by the PC, which then boots another program.
to most PCs. On power on, the XS1-L1 boots from the on-board flash memory. The
No UART hardware is provided. Instead, two UART pins are mapped to ports, as
shown in the table below.
If a UART is required, it can be implemented in software by sampling and driving
these ports at the required rate. The XTAG-2 performs a UART-to-USB conversion on
these pins, which is interfaced by a proprietary XMOS terminal emulator.
