Early termination of SPI using burst mode reads in an ADIS16364

I am starting into the interface integration from a PIC processor to an ADIS16364 sensor.  I plan to use the SPI burst mode read function but do not need the entire list of parameters available.  Can I simply terminate the SPI cycle after receiving the last desired parameter by raising CS* back high or is it necessary to read the entire list available for burst mode.  This is a processor scheduling issue and if I can save some time (SPI reads are sloooow) I can cut off the process.  From reading in other posts it would appear that taking CS* back high clears and resets the SPI interface for the next cycle.  Does it have any negative affect on the data if some of the parameters are never read or is this a reasonable approach?  I need only the 3 accel and 3 gyro data values.  I know that I have to read the SUPPLY_OUT first, but I can just toss that away, then stop reading after ZACCL_OUT.
