Other Parts Discussed in Thread: MSP430F5438A
After looking in both the MSP430x5xx/MSP430x6xx Family User's Guide (SLAU208G) and the MSP430F5438A data sheet, I have been unable to find what clock sources, other than "ADC12CLK" can be used to generate the SHI signal. The block diagram in page 467 of the user's guide shows three other, unidentified, clock sources and references the data sheet, but I could not find what these are in the data sheet.
Where can I find this information, as well as the SHSx codes that select them?
