C8051F52x/F52xA/F53x/F53xA
(F52x/F52xA) for the external CNVSTR signal, 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 13.3
shows the Crossbar Decoder priority with no Port pins skipped (P0SKIP, P1SKIP); Figure 13.4 shows the
Crossbar Decoder priority with the XTAL1 (P1.0) and XTAL2 (P1.1) pins skipped (P1SKIP = 0x03).
Important Note on UART Pins: On C8051F52xA/53xA devices, the UART pins must be skipped if the
UART is enabled in order for peripherals to appear on port pins beyond the UART on the crossbar. For
example, with the SPI and UART enabled on the crossbar with the SPI on P1.0-P1.3, the UART pins must
be skipped using P0SKIP for the SPI pins to appear correctly.

When these signals are enabled, the Crossbar must be manually configured
to skip their corresponding port pins.
