The 6532 has *2* 8-bits I/O ports similar to the 6522. The nice thing about this particular design is that you can assign pins as input AND output on the same port simulteaneously through a register. That means that you can assign some pins as input, and some as outputs. This is a very neat feature as you can use one port and transfer data using 4 bits for each side. Data transfer would be serial and could include a simple form of "handshaking".
