  1. Hello. We are using MSP430F6723, and we want to achieve 20 uA of current consumption. There is a problem with hardware SPI. SMCLK doesn't stop after reading from SPI is finished. If I'm not mistaken, it doesn't stop if UCBUSY = 1. I don't care about UCBUSY behavior, but I have huge additional current consumption becasue SMCLK doesn't stop. Therefore, I have to use a software implementation of SPI. But in this case I need 160 uSec to read 32-bit word. With hw SPI it takes 30-40 uSec (4 times faster). It also costs 2 uA additional consumption. This value
