Qtouch sensor trouble

Hello everubody

I have some troubles wiring the QT1011 sensor while in the datasheet they are saying you can obtain Heartbeat rate but i didn’t understand the port.M…x and the port.M.y are they digital or anologic I/O
you can check the datasheet in the attachement Page 10 and 11
