_COUNTER[7:0]
R/W 0h
Config for STX 3,4/7,8
In JESD-B. Register is used as init value of o_mf_counter in
sysref block
In JESD-C,
[4:0] - used to reset blk_ctr
[9:5] - used to reset mblk_ctr
Value has to be multiples of 8. All values cannot be handled
due to assumption of frame_end and multiframe_end in a
specific pattern
