XMOS
5.2 Sleep mode
The XCore can be made to completely switch off its core power, until an external
signal is received or an internal timer expires. This requires an external FET that
gates the core power supply (see Figure 4).
Users of the sleep mode should note the following:

• For minimal leakage, when the XCore is switched off, the internal pull-
downs on IO pads cannot be relied on. The system should maintain all I/O
