Forum Post: MSP432P401R: CS_setDCOFrequency driver function does not accept 40MHz since upgrade to REV C, red experimenter board (worked on REV B, black board)

Part Number: MSP432P401R Since the upgrade from REV B to REV C, trying to set the DCO to 40MHz using the CS_setDCOFrequency driver sends me to the fault ISR and I get the following message as well. CORTEX_M4_0: Trouble Halting Target CPU: (Error -1266 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 6.0.504.2) I get the same issue/warnings using the MSP432ware provided "cs_dco_frequency_tune" sample project when I try to set up the DCO to 40MHz. Is this a bug with the driver or is it a new limitation in the Silicon? Any help is very much appreciated. -Edgar.
