6748, SPI, SPILVL register question

in the document sprufm4g.pdf the description of the SPILVL register includes fields that are a single bit, but one of the options is reserved.  this would leave me to believe that i have only one option if i ever write to this register (since the rest of the bits are reserved) but HO! the default value for this register is the reserved values!  I am a little confused about how i should handle this register. is writing all 0's to this register not valid?  do i have to either turn all the interrupts on to INT1 or none of them at all?

    As far as I know, you should be able to program the interrupts you are not concerned about as 0.  You do not have to configure all fields to 1.

    Hi,

    As per my understanding, all 0's can be written into the register but that will not have any effect as there is no functionality specified for the same.  You can write 1 to those bits of the register which you want to map to the INT1.
