XS1-L1 128TQFP Datasheet (2.2)
XS1-L System
The MODE pins must be static for reliable operation.
When booting the XS1-L1 device from a SPI interface, the SPI device must be connected
Bits [1:0] control the PLL boot mode according to the following table:
If secure boot from OTP is enabled by programming the OTP, the boot mode indicated
on the MODE[3:2] pins is ignored. For further details on booting XCores see the
DEBUG This pin is used to synchronize the debugging of multiple XS1 devices.

This pin can operate in both output and input mode. In output mode and
when configured to do so, DEBUG is driven low by the device when the XCore
XCore into debug mode. Software can set the behavior of the XCore based
processor hits a debug break point. Prior to this point the pin will be tri-stated.
In input mode and when configured to do so, driving this pin low will put the
on this pin. If multi-device debug is not required then this pin can be left
unconnected.
must be activated for at least 5us after the power supplies are stable to ensure
reliable booting. Following a reset the PLL re-establishes lock after which the
device boots up according to the boot mode (see MODE).
