Bits 31–14
RX_TIME_END Correlation Stop Time—Sets the middle 6 bits of the
Bits 13–8 search window end time. The MS_CLK is a 12-bit
clock that counts from 0 (0x000) to 2499 (0x9C3). The
RX_TIME_END field defines the bits x.
MS_CLK[11:0] = 101x xxxx x000.

the search window end time ranges
from 64µs to 127µs.
RX_TIME_START can range from
00000 to 11000, which means that
the search window start time ranges
from 288µs and 312µs.
