18.1. Ports 0 through 3 and the Priority Crossbar Decoder
The Priority Crossbar Decoder, or “Crossbar”, allocates and assigns Port pins on Port 0 through Port 3 to
the digital peripherals (UARTs, SMBus, PCA, Timers, etc.) on the device using a priority order. The Port
pins are allocated in order starting with P0.0 and continue through P3.7 (on the C8051F060/2/4/6) or P2.7
(on the C8051F061/3/5/7) if necessary. The digital peripherals are assigned Port pins in a priority order
which is listed in Figure 18.3, with UART0 having the highest priority and CNVSTR2 having the lowest pri-
ority.
18.1.1. Crossbar Pin Assignment and Allocation
The Crossbar assigns Port pins to a peripheral if the corresponding enable bits of the peripheral are set to
a logic 1 in the Crossbar configuration registers XBR0, XBR1, XBR2, and XBR3, shown in Figure 18.5,
Figure 18.6, Figure 18.7, and Figure 18.8. For example, if the UART0EN bit (XBR0.2) is set to a logic 1,
the TX0 and RX0 pins will be mapped to P0.0 and P0.1 respectively. Because UART0 has the highest pri-
ority, its pins will always be mapped to P0.0 and P0.1 when UART0EN is set to a logic 1. If a digital periph-
