XS1-G4 144BGA Datasheet (3.5)
The XS1-G family supports a generic 5pin JTAG interface, which can be used to
The JTAG connectors on the XCore are:
The JTAG controller has access to the following registers for an XCore:
2.3 JTAG Operation
provide hardware testing including:
Each XCore and Switch has a JTAG controller with a 10-bit instruction register (IR) and
a 32-bit data register (DR). A mux controller selects the XCore the TMS is routed to,
and which device TDO is wired to the chip level output. TDO can output in tristate in
accordance with the JTAG specification. The JTAG controller supports the following
commands:
