This function handles the transition of the EZI2C SCB into and out of Deep Sleep mode.
It prevents the device from entering Deep Sleep mode if the EZI2C slave is actively communicating. The following behavior of the EZI2C depends on whether the SCB block is wakeup-capable:
This function must be called during execution of Cy_SysPm_CpuEnterDeepSleep. To do this, register this function as a callback before calling Cy_SysPm_CpuEnterDeepSleep : specify CY_SYSPM_DEEPSLEEP as the callback type and call Cy_SysPm_RegisterCallback.

This function handles the transition of the EZI2C SCB block into Hibernate mode.
It prevents the device from entering Hibernate mode if the EZI2C slave is actively communicating. If the EZI2C is ready to enter Hibernate mode, it is disabled. If the device fails to enter Hibernate mode, the EZI2C is enabled. While the EZI2C is disabled, it stops driving the output and ignores the inputs. The slave NACKs all incoming addresses.
This function must be called during execution of Cy_SysPm_SystemEnterHibernate. To do this, register this function as a callback before calling Cy_SysPm_SystemEnterHibernate : specify CY_SYSPM_HIBERNATE as the callback type and call Cy_SysPm_RegisterCallback.
