5.16.2.1 5-Wire UART Topology
Figure 5-10 shows the typical 5-wire UART topology comprised of four standard UART lines plus one IRQ
line from the device to the host controller to allow efficient low power mode.
Figure 5-10 shows the typical and recommended UART topology because it offers the maximum
communication reliability and flexibility between the host and the SimpleLink device.
Figure 5-10. Typical 5-Wire UART Topology
5.16.2.2 4-Wire UART Topology
The 4-wire UART topology eliminates the host IRQ line (see Figure 5-11). Using this topology requires
one of the following conditions to be met:
• Host is always awake or active.
• Host goes to sleep, but the UART module has receiver start-edge detection for automatic wake up and
does not lose data.
Figure 5-11. 4-Wire UART Configuration
5.16.2.3 3-Wire UART Topology
The 3-wire UART topology requires only the following lines (see Figure 5-12).
• RX
• TX
• nCTS
