mma8652 fifo trigger mode behaviour

i'd like to use FIFO in trigger mode. i'd like to record 10 samples before transient event and the rest (22 samples) after.

i also want the transient event to wake up the device and start sampling at higher rate (800Hz when awake and 50 Hz when sleep).

i saw in the datasheet that FIFO is flushed whenever the DR is switched due to sleep-wake transition. is that includes working with FIFO in trigger mode?

if yes, does it means there is no way to use DR higher than 50 Hz in FIFO trigger mode?
