28. Port Input/Output
Digital and analog resources are available through 64 I/O pins. Each of the Port pins P0.0–P2.7 can be
defined as general-purpose I/O (GPIO), assigned to one of the internal digital resources, or assigned to an
analog function as shown in Figure 28.4. The designer has complete control over which functions are
assigned, limited only by the number of physical I/O pins. This resource assignment flexibility is achieved
through the use of a Priority Crossbar Decoder. The state of a Port I/O pin can always be read in the corre-
sponding Port latch, regardless of the Crossbar settings.
The Crossbar assigns the selected internal digital resources to the I/O pins based on the Priority Decoder.
The registers XBR0 and XBR1, defined in SFR Definition 28.1 and SFR Definition 28.2, are used to select
internal digital functions.
All Port I/Os except P0.3 are tolerant of voltages up to 2 V above the V
the Port cell circuit). The Port I/O cells are configured as either push-pull or open-drain in the Port Output
Mode registers (PnMDOUT, where n = 0,1). Complete Electrical Specifications for Port I/O are given in
Section “9. Electrical Characteristics” on page 47.
