5.6 Port 5
Port 5 is a 6-bit input/output port that also provides the input and output pins for the serial
communication interface. The pin functions depend on control bits in the serial control registers.
Pins not used for serial communication are available for general-purpose input/output. Table 5-10
lists the pin functions, which are the same in both the expanded and single-chip modes.
