ASRC Frame Threshold (ASRC_FTC):
The 16 bit frame threshold value needs to be
written here. Every time the frame count matches the frame threshold a snapshot of the
free running timer will be taken and stored in the snapshot register. An interrupt will be
generated as well. If the frame threshold is changed on the fly during operation then the
following behavior is expected. Previous value = A, New value value = B If B ) A : The
frame counter keeps counting up to the new value. Nothing happens when the frame
counter reaches the old value of A. If B ( A : The frame counter resets to zero on the
next frame. No interrupt or snapshot is generated in this case.

ASRC Frame Snapshot (ASRC_TIMER_SNAPSHOT):
This field holds the 32 bit
snapshot value. The value is noted on the clock cycle when the frame threshold matches
the frame count.
