There are thirty-two Backplane Input Delay Registers (BIDR0 to BIDR31).
When the SMPL_MODE bit in the Control Register is LOW, the input data sampling point defaults to the 3/4 bit
location and BIDR0 to BIDR31 define the input bit and fractional bit delay of each Backplane stream. The possible
bit delay adjustment is up to 7
When the SMPL_MODE bit is HIGH, BIDR0 to BIDR31 define the input bit sampling point as well as the integer bit
delay of each Backplane stream. The input bit sampling point can be adjusted in 1/4 bit increments. The bit delay
can be adjusted in 1-bit increments from 0 to 7 bits.
The BIDR0 to BIDR31 registers are configured as follows:
Backplane Non-32 Mbps Mode,
n = 0 to 15 for Backplane
(where n = 0 to 31 for
Backplane Input Bit Delay Registers (BIDR0 to BIDR31)
32 Mbps Mode)

Backplane Input Bit Delay Register
When SMPL_MODE = LOW, the binary value of these
bits refers to the input bit and fractional bit delay value (0
to 7
When SMPL_MODE = HIGH, the binary value of BID[1:0]
refers to the input bit sampling point (
refer to the integer bit delay value (0 to 7 bits).
