UART0 Module Signals and PB[4:0]
between the corresponding port pin or the other functions that may be multiplexed onto the
pin. After reset all pins multiplexed with GPIO signals default to inputs.
Port A general purpose I/O, PA[15:8] are multiplexed with PLIC TDM port 1 pins.
Port A general purpose I/O, PA[6:0] are multiplexed with USB module signals. PA7 is
multiplexed with QSPI_CS3 and DOUT3.
Port B general purpose I/O, PB[4:0] are multiplexed with the UART0 interface pins. If the
UART0 interface is enabled, PB[4:0] are unavailable. PB5 is multiplexed with TA. PB6 is
dedicated. PB7 is multiplexed with TOUT0.
Port B general purpose I/O, PB[15:8] are multiplexed with the Ethernet interface pins. If
the Ethernet interface is enabled, PB[15:8] are unavailable.
Port C general purpose I/O, PC[15:0] are multiplexed with D[15:0]. When 32-bit wide bus
mode is selected, port C is unavailable.
19.10 UART0 Module Signals and PB[4:0]
The UART0 module uses the signals in this section for data and clock signals.
These signals are multiplexed with the GPIO port B signals PB[4:0].
19.10.1 Transmit Serial Data Output (URT0_TxD/PB0)
UART0 mode: URT0_TxD is the transmitter serial data output for the UART0 module. The
output is held high (mark condition) when the transmitter is disabled, idle, or in the local
loopback mode. Data is shifted out, lsb first, on this pin at the falling edge of the serial clock
source.
Port B mode: This pin can also be configured as the PB0 I/O.
19.10.2 Receive Serial Data Input (URT0_RxD/PB1)
UART0 mode: URT0_RxD is the receiver serial data input for the UART0 module. Data
received on this pin is sampled on the rising edge of the serial clock source lsb first. When
the UART0 clock is stopped for power-down mode, any transition on this pin restarts it.
Port B mode: This pin can also be configured as the PB1 I/O.
19.10.3 Clear-to-Send (URT0_CTS/PB2)
UART0 mode: Asserting the URT0_CTS input is the clear-to-send (CTS) input, indicating
to the UART0 module that it can begin data transmission.
Port B mode: This pin can also be configured as the PB2 I/O.
