COMPB - LED Toggle in LPM4, Vcomp_0 is compared against Vcomp_1 voltage

Use CompB and internal reference to determine if input 'Vcompare' is high of low. When Vcomp_0 exceeds Vcomp_1 CBOUT goes high and when Vcomp_0 is less than Vcomp_1 then CBOUT goes low. Connect P1.6/CBOUT to P1.0 externally to see the LED toggle accordingly.

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• COMPB peripheral
• GPIO Port peripheral
• CB0
• CB1
• CBOUT

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• None.
