The AD and RTC functions are turned on when developing a new product with the MSP430FR6972, where both the operating current and the sleep current are large, 360uA and 99uA, respectively. Previous products did not use these two functions, operating at only 200 uA and sleeping at only 0.9 uA.
The customer would like to know the following 3 questions:
1. If the AD module is turned off after sleep, how to restart the AD module after waking up?
2. Is it possible to reference a reference DEMO?
3. Since there is a wait time for the AD module to settle with an internal reference voltage of 1.2V when the AD module is restarted, how long is this time? Too long will affect a feature of the product.
Thanks a lot!
