Bug in MSP430 uslib.c #1
Description
A bug in MSP430 reported by @lujinhao fw for both wulpus and wulpus-pro.
The impact is fairly low: probably would only save <1mA current draw but should improve the reliability a bit.
"fw/msp430/wulpus_msp430_firmware/uslib/uslib.c#L505
Here, bitwise or makes more sense.
This bug leads to delay of the rest code of the function till the next slow_CCR0 timer (since #define TIMER_SLOW_CCR0_EVENT (1<<0)).
Power wise, the USS module is turned off already in the call back function saphSeqAcqDoneCallback. So I guess the power consumption difference is probably only between LPM0 and LPM3 which is about 200uA (there could be something I missed that draws more current)."
