Hello,

Any pin (port) can be used to wake a device up from the deep sleep mode.

Use the Global Signal Reference component and set it to Combined Port Interrupt (AllPortInt).

This is a hardware resource used to detect if any of the interrupt enabled pins triggered an interrupt. It is a separate resource from the dedicated port interrupts, and it has the capability to wake up the chip from deep-sleep and hibernate modes.

To use the Combined Port Interrupt option, configure the Interrupt parameter of the Pins Component to specify your trigger condition.  If you connect an interrupt Component to this terminal, then that port will use the dedicated port interrupt and also allow the pin to become a source for the Combined port Interrupt.

Hi All:

    If the dedicated Port Interrupts are able to waking up the chip from deep-sleep,  I want to know which ports allow the dedicated ports to wake up the chip from deep-sleep for the CY8C4147AZI-S455
