12.4.6.1 USART0
The SFR bit PERCFG.U0CFG selects whether
to use alternative 1 or alternative 2 locations.
In Table 50, the USART0 signals are shown
as follows:
SPI:
• SCK: C
• SSN: SS¹⁵
• MOSI: MO
• MISO: MI
UART:
• RXDATA: RX
• TXDATA: TX
• RTS: RT
• CTS: CT
15 _{SSN should only be configured as a}
peripheral when using SPI slave mode
P2DIR.PRIP0 selects the order of
precedence when assigning two peripherals to
the same pin location on P0. When set to 00,
USART0 has precedence if both USART0 and
USART1 are assigned to the same pins. Note
that if USART0 is configured to operate in
UART mode with hardware flow control
disabled, USART1 or timer 1 will have
precedence to use ports P0_4 and P0_5. It is
the user’s responsibility to not assign more
than two peripherals to the same pin locations,
as P2DIR.PRIP0 will not give a conclusive
order of precedence if more than two
peripherals are in conflict on a pin.
P2SEL.PRI3P1,
P2SEL.PRI2P1,
P2SEL.PRI1P1, and P2SEL.PRI0P1 select
the order of precedence when assigning two,
and in some cases three, peripherals to P1.
An example is if both the USARTs are assign
to P1 together with Timer 1 (channel 2, 1, and
0). By setting both PRI3P1 and PRI0P1 to 0,
USART0 will have precedence. Note that if
USART0 is configured to operate in UART
mode with hardware flow control disabled,
USART1 can still use P1_7 and P1_6, while
Timer 1 can use P1_2, P1_1, and P1_0. Also
