18. Port Input/Output
The devices are fully integrated mixed-signal System on a Chip MCUs with 64 digital I/O pins (100-pin
TQFP packaging) or 32 digital I/O pins (64-pin TQFP packaging), organized as 8-bit Ports. All ports are
both bit- and byte-addressable through their corresponding Port Data registers. All Port pins are 5 V-toler-
ant, and all support configurable Open-Drain or Push-Pull output modes and weak pullups. A block dia-
gram of the Port I/O cell is shown in Figure 18.1. Complete Electrical Specifications for the Port I/O pins
are given in Table 18.1.
