Figure 23.6. Priority Crossbar Decoder Example 2—Skipping Pins
In this example, the crossbar is configured to assign the UART TX0 and
RX0 signals, the SPI signals, and the PCA signals. Note that the SPI
signals are assigned as multiple signals. Additionally, pins P0.0, P0.2, and
P0.3 are configured to be skipped using the P0SKIP register.

respectively.
All unassigned pins, including those skipped by XBR0 can be used as
GPIO or for other non-crossbar functions.
Notes:
1. P1.4-P1.7 are not available on 16-pin packages.
2. NSS is only pinned out when the SPI is in 4-wire mode.
