Registers XBR1 and XBR2 are used to assign the digital I/O resources to the physical I/O Port pins. Note
that when the SMBus is selected, the crossbar assigns both pins associated with the SMBus (SDA and
SCL). UART0 pin assignments are fixed for bootloading purposes: UART TX0 is always assigned to P0.4;
UART RX0 is always assigned to P0.5. Standard Port I/Os appear contiguously after the prioritized func-
tions have been assigned.

In this example, the crossbar is configured to
assign the UART TX0 and RX0 signals, the
SMBus signals, and the SYSCLK signal. Note
that the SMBus signals are assigned as a pair.
Additionally, pins P0.0 and P0.3 are configured
to be skipped using the XBR0 register.

All unassigned pins, including those skipped by
