COMPB - LED Toggle in LPM4, Ultra Low Power Mode, Input compared against 0.5*Vcc

Use CompB and shared reference to determine if input 'Vcompare' is high of low. When Vcompare exceeds Vcc*1/2 CBOUT goes high and when Vcompare is less than Vcc*1/2 then CBOUT goes low. Connect P1.6/CBOUT to P1.0 externally to see the LED toggle accordingly.

   ------------------

/|| | | | | –|RST P6.0/CB0|<- Vcompare | P1.6/CBOUT|--> 'high'(Vcompare>Vcc*1/2); 'low'(Vcompare<Vcc*1/2) | | | | P1.0|_| LED 'ON'(Vcompare>Vcc*1/2); 'OFF'(Vcompare<Vcc*1/2) | |

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
• 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.
