Control corresponds to the Data Direction – DD Register, and the Pull-up Enable – PUExn – cor-
responds to logic expression PUD · DDxn · PORTxn.
Digital alternate port functions are connected outside the dotted box in
to make the scan chain read the actual pin value. For Analog function, there is a direct connec-
tion from the external pin to the analog circuit, and a scan chain is inserted on the interface
between the digital logic and the analog circuitry.
