XMOS
8 Power Connector [D] and Regulator [K]
The XC-2 requires connection from an external 5V power supply. The voltage
is converted by the on-board regulator to the 1V and 3V3 supplies used by the
components.
9 XSYS Connector [H]
The XC-2 includes an XSYS connector, which can be used to boot and debug
code on all of the XS1-G4’s processors. The XSYS connector provides pins for
JTAG control, system reset, processor debug, two UART links and one XMOS
Link. The routing of these I/O pins along with the power pins is shown below.
The XMOS XTAG connector converts between XSYS and USB 2.0, allowing the
XC-2 to be connected to most PCs. On power on, the XS1-G4 boots from the
on-board flash memory. The XS1-G4 can then be put into JTAG mode by the
PC, which then boots another program.
No UART hardware is provided. Instead, two UART pins are mapped to ports,
as shown in the table below.
