There are some inconsistencies in the datasheet for the MSP430FR5962. There is a generalized statement that all port x.y can be configured as interrupts. However the table 6-4 (Interrupt priority) is missing information for some ports, which concerns me that this may not be entirely true.
For example Port 0 is missing from table altogether, in other MSP430 datasheets this is typically the port with the highest priority. Port 5 only shows priority for bits 0, 1, and 2 and not 3-7.
Thanks for your help.
