There are thirty-two Local Input Delay Registers (LIDR0 to LIDR31).
When the SMPL_MODE bit in the Control Register is LOW, the input data sampling point defaults to the 3/4 bit
location and LIDR0 to LIDR31 define the input bit and fractional bit delay of each Local stream. The possible bit
delay adjustment is up to 7
When the SMPL_MODE bit is HIGH, LIDR0 to LIDR31 define the input bit sampling point as well as the integer bit
delay of each Local 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 LIDR0 to LIDR31 registers are configured as follows:

Local 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 LID[1:0]
refers to the input bit sampling point (
refer to the integer bit delay value (0 to 7 bits).
