Registers XBR0, 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); and similarly when the UART, CAN or LIN are selected, the Crossbar assigns both pins
associated with the peripheral (TX and RX). UART0 pin assignments are fixed for bootloading purposes:
UART TX0 is always assigned to P0.4; UART RX0 is always assigned to P0.5. CAN0 pin assignments are
fixed to P0.6 for CAN_TX and P0.7 for CAN_RX. Standard Port I/Os appear contiguously after the priori-
tized functions have been assigned.
Important Note: The SPI can be operated in either 3-wire or 4-wire modes, pending the state of the
NSSMD1–NSSMD0 bits in register SPI0CN. According to the SPI mode, the NSS signal may or may not
be routed to a Port pin.
As an example configuration, if CAN0, SPI0 in 4-wire mode, and PCA0 Modules 0, 1, and 2 are enabled on
the crossbar with P0.1, P0.2, and P0.5 skipped, the registers should be set as follows: XBR0 = 0x06
(CAN0 and SPI0 enabled), XBR1 = 0x0C (PCA0 modules 0, 1, and 2 enabled), XBR2 = 0x40 (Crossbar
enabled), and P0SKIP = 0x26 (P0.1, P0.2, and P0.5 skipped). The resulting crossbar would look as shown
in Figure 19.4.
