Figure 5 – UART lines connected between the USB MCU and the onboard MSP430 MCU.
CTS and RTS lines are dotted to indicate that the USB MCU standard firmware only
implements a two-line UART interface to the MSP430 MCU.
NOTE: Figure 5 shows the four hardware connected UART lines the USB MCU and the
MSP430 MCU. The MSP430 does not support hardware flow control (RTS and CTS lines).
Such support must be manually implemented in the MSP430 software. To ease MSP430
application development, the standard USB MCU firmware uses a two-line UART interface to
the MSP430, i.e. hardware flow control is not implemented.

6.1.3 Disabled Mode

Disabled Mode is obtained by setting hardware switch S2 on the EB to "Disable" position (see
Table 4). The position of S1 is disregarded by the USB MCU when S2 is in the "Disable" position.
In Disabled Mode, the USB MCU is in power-down mode and no USB communication is possible
between a PC and the EB. It is however still possible to power the EB via the USB cable, see
section 6.3.2.
