Port 5 pins block diagram
Port 5 registers
Port 5 registers include port 5 data register (PDR5), port 5 direction register (DDR5), and analog input
permission register (ADER).
Analog input permission register (ADER) allows or disallows input of analog signal to the analog input pin.
The bits configuring the register correspond to port 5 pins on a one-to-one basis.
