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

Port

Processor

X0D50

P32A1

RST_N

J3 and J4 connectors

The xTAG v3.0 has two additional connectors. These are reserved for future use.

24MHz Crystal Oscillator

The XS1-U8 is clocked at 24MHz by a crystal oscillator on the card. The processor

is clocked at 500MHz and the I/O ports at 100MHz, by an on-chip phase locked
loop (PLL).
