0
After ‘1’ is written to this bit, a read or write operation is implemented.
RW

0
This bit selects read or write operation
= 0: write to RAM
= 1: read from RAM
UI[1:0]
5-4
00
These bits specify the unit interval address. There are 4 unit intervals.
= 00: UI address is 0 (The most left UI)
= 01: UI address is 1
= 10: UI address is 2
= 11: UI address is 3
SAMP[3:0]
3-0
0000
These bits specify the sample address. Each UI has 16 samples.
= 0000: sample address is 0 (The most left Sample)
= 0001: sample address is 1
= 0010: sample address is 2
......
= 1110: sample address is 14
= 1111: sample address is 15

0000000
In Indirect Write operation, the WDAT[6:0] will be loaded to the pulse template RAM, specifying the amplitude of
the Sample.
After an Indirect Read operation, the amplitude data of the Sample in the pulse template RAM will be output to the
WDAT[6:0].

00
Receiver path decoding selection
= 00: receive data is HDB3 (E1) / B8ZS (T1/J1) decoded and output on RDn with single rail NRZ format
= 01: receive data is AMI decoded and output on RDn with single rail NRZ format
= 10: decoder is bypassed, re-timed dual rail data with NRZ format output on RDPn/RDNn (dual rail mode with
clock recovery)
= 11: both CDR and decoder blocks are bypassed, slicer data with RZ format output on RDPn/RDNn (slicer mode)
