Carriage Return/an Enter command followed by any of the above instructions results in the
following:
LED ON: Turns on the LED and returns the phrase "LED is ON" back to HyperTerminal
LED OFF: Turns off the LED and returns the phrase "LED is OFF" back to HyperTerminal
LED TOGGLE – SLOW: Turns on the timer used to toggle LED with a large period and returns
the phrase "LED is toggling slowly" back to HyperTerminal
LED TOGGLE – FAST: Turns on the timer used to toggle LED with a smaller period and
returns the phrase "LED is toggling fast" back to HyperTerminal
NOTE:
In case any other phrase (other than the ones discussed above) is typed in the
HyperTerminal followed by the enter command, “No such command!” is returned back to the
HyperTerminal.
The CDC and HID stacks provide a number of useful code examples that can serve as a good
starting point for USB development.

Special Considerations for the MSP430F66xx Device
The document
MSP430x5xx Overview Comparison to MSP430x2xx and MSP430x4xx
provides
a high level overview of migration concerns when moving from an MSP430F2xx/4xx family
device to an MSP430F5xx/F6xx device. In addition the section below outlines some specifics
about enhancements in select modules in the F66xx device family.
5.1
Memory Map
The MSP430F66xx family has a 1-MB unified memory map with expanded peripheral space
over previous families (see Table 1).
•
Peripheral space is eight times the size available in the MSP430x2xx/MSP430x4xx
families.
•
Info A is two times the size available in the MSP430x2xx/MSP430x4xx families.
•
Interrupt vector space is two times the size available in the MSP430x2xx/MSP430x4xx
families.
•
Extra 2KB USB RAM which can be used by the application code if the USB module is not
in use.
