XMOS
If a UART is required, it can be implemented in software by sampling and driving
these ports at the required rate. The XTAG performs a UART-to-USB conversion
on these pins, presenting a virtual COM port to the PC that can be interfaced via
a terminal emulator.
10 SPI Flash Memory [I]
The XC-2 provides 4Mbit of Serial Peripheral Interface (SPI) flash memory, which
is interfaced by the four 1-bit connections described in the table below.
The Development Tools include the XFLASH utility for programming compiled
programs into the flash memory. XC-2 designs may also access the flash mem-
ory at run-time by interfacing with the above ports.
11 25MHz Crystal Oscillator [L]
The XS1-G4 is clocked at 25MHz by a crystal oscillator on the card. Each pro-
cessor is clocked at 400MHz, the I/O ports at 100MHz, by an on-chip phase-
locked loop (PLL).
12 PLL Status LED [M]
The PLL status LED remains off until the on-chip PLL has locked. Once the
PLL clock is stable, the LED is illuminated red, indicating that the processor has
power and the clock is running.
