     This sketch is universal and worksn on both Portenta C33 and H7. 
 
     On the the Portenta C33 you can select any of the supported pins (A0, A1, A2, A3, A4, A5, D4, D7) to wake up the board from standby mode, 
-    but on the Portenta H7 only GPIO0 can be used to wake up the board from standby mode. GPIO0 is available trough the High Density Connectors and you need a breakout board to access it.

     This example demonstrates how to  wake up the Portenta C33 from standby mode using the included RTC (Real Time Clock).
     The device will go to sleep for 1 second and then wake up. When the device is awake you will see the board's blue LED turned on. 
-    Effectivelly, you will get the same effect as with blink. 
+    Effectively, you will get the same effect as with blink. 
 
     On the Portenta C33 with the peripherals turned off you can expect around 60uA of current consumption in standby mode.
     The example also turns off the peripherals before going to sleep and turns them back on after waking up.
