LCD Charge Pump during RX (CC430F6137 Errata) #56

Closed travisgoodspeed closed 6 years ago

The LCD charge pump automatically turns off during radio transmission when LCDBCPCTL&1 to reduce interference and maintain sensitivity. This causes the display to dim down and eventually disappear during long receive periods.

Close this issue when we have a way to manage this register, keeping the display active where possible. The solution will likely be different for each protocol, and perhaps its performance impact isn't enough to worry about.

I've not seen this bug on the CC430F6147, so I'm declaring the bug to be an undocumented hardware errata. Closing as WONTFIX.
