Is the PSOC 4 ( CY8C4045AZI-S413 ) I2C port only available in deep sleep mode ?
Will I still be able to use it in active mode as well ? The GPIO pin mux only list the I2C ressources in the deep sleep state column .
Thank you very much . Have a great day.
I2C works only in active mode, does not work during DeepSleep mode but can be used as a wakeup resource.

Because IMO is stopped during active mode and it is running only with low frequency clock.
As a wakeup resource, it shifts from DeepSleep mode to Active mode only when an I2C address match occurs.
