12.1. Priority Crossbar Decoder
The Priority Crossbar Decoder (Figure 12.3) assigns a priority to each I/O function, starting at the top with
UART0. When a digital resource is selected, the least significant unassigned Port pin is assigned to that
resource (excluding UART0, which is always at pins 4 and 5). If a Port pin is assigned, the Crossbar skips
that pin when assigning the next selected resource. Additionally, the Crossbar will skip Port pins whose
associated bits in the XBR0 register are set. The XBR0 register allows software to skip Port pins that are to
be used for analog input or GPIO.
Important Note on Crossbar Configuration: If a Port pin is claimed by a peripheral without use of the
Crossbar, its corresponding XBR0 bit should be set. This applies to P0.0 if VREF is enabled, P0.3 and/or
P0.2 if the external oscillator circuit is enabled, P0.6 if the ADC is configured to use the external conversion
start signal (CNVSTR), and any selected ADC or Comparator inputs. The Crossbar skips selected pins as
if they were already assigned, and moves to the next unassigned pin. Figure 12.3 shows the Crossbar
Decoder priority with no Port pins skipped (XBR0 = 0x00); Figure 12.4 shows the Crossbar Decoder prior-
ity with pins 6 and 2 skipped (XBR0 = 0x44).

Special Function Signals are not assigned by the crossbar.
When these signals are enabled, the CrossBar must be
manually configured to skip their corresponding port pins.

signal.
