Serial Module Signals
Timer Module Signals
The RXD0/GPIO46 and SDA1/RXD1/GPIO44 are the inputs on which serial data is received by the
DUART. Data is sampled on RxD[1:0] on the rising edge of the serial clock source, with the least
significant bit received first.
The DUART transmits serial data on the TXD0/GPIO45 and SCL1/TXD1/GPIO10 output signals. Data
is transmitted on the falling edge of the serial clock source, with the least significant bit transmitted (LSB)
first. When no data is being transmitted or the transmitter is disabled, these two signals are held high.
TxD[1:0] are also held high in local loopback mode.
The DDATA3/RTS0/GP104 and DDATA1/RTS1/SDATA2_BS2/GPIO2 request-to-send outputs indicate
to the peripheral device that the DUART is ready to send data and requires a clear-to-send signal to
initiate transfer.
Peripherals drive the DDATA2/CTS0/GPIO3 and DDATA0/CTS1/SDATA0_SDIO1/GPIO1 inputs to
indicate to the SCF5250 serial module that it can begin data transmission.
The SDATAO1/TOUT0/GPIO18 programmable output pulse or toggle on various timer events.
