XTAG-2 Hardware Manual (1.0)
4.2 XMOS Link Configuration
Some of the I/O pins on the processor are configured as a duplex 2-bit serial XMOS
Link. The mapping of XMOS Link to the pins is shown in the table below:
4.3 JTAG Configuration
Some of the I/O pins on the processor are driven by the JTAG signals. The mapping
of the signals to the pins is shown in the table below:
4.4 System Reset
The system reset signal is mapped to a 1-bit port on the processor as described
below. It is used as an output to reset the target processor from the debugger
5 13MHz Crystal Oscillator
The XS1-L1 is clocked at 13MHz by a crystal oscillator on the card. The processor is
clocked at 400MHz and the I/O ports at 100MHz, by an on-chip phaselocked loop
(PLL).
