Hi all,
In CC430 RF Examples, there are these lines:
// Increase PMMCOREV level to 2 for proper radio operation
SetVCore(2);
I tried using level 2 as the example suggests. The transmitter worked fine with a new battery but it went into BOR state (kept resetting) very early when the battery got just a little bit low.
I tried level 0 (just use the default setting) and my transmitter worked fine in a wide voltage range (could go as low as 1.9).
The transmitter was running at 5.01MHz, the battery was a coin cell CR2477 (3V).
So my question is: Do we really need to set VCore to level 2 for proper radio operation? Why isn't this mentioned anywhere in the user guide?
Someone has posted a similar question but had no final answer yet.
Thank you.
