How long does it take for DCO to settle at 16MHz, referenced to REFO, when set to this configuration shortly following BOR? (w/ MSP430FR2032 & MSP430FR2033)
In the datasheet I see 120ms listed in table 5-4, with XT1 as reference. However I don’t see a spec listed with REFO as reference.
Driverlib function CS_initFLLSettle() includes a fixed delay of 52ms, which appears to be insufficient.
Please clarify the best practices for using the FLL to set the DCO when using REFO after a BOR.
