Position Description Reset State
Bit 01 Fail Counters Clear. 0x0
Writing a 1 to this bit creates a pulse to clear the fail counters for all channels.
Writing a 0 has no affect.
Bit 00
Soft Reset. Writing this register bit to a Logic 1 causes the ADATE207 to generate a software reset. This
is logically equivalent to a hard reset via the I_RESET_B pin. All logic and registers
are reset.

Name: Round Trip Delay Value
Address: 0x1A
Type: Read/Write

Bits[15:05] Not Used. 0x000
Bits[4:00]
Round Trip Delay Value. Programs the round-trip delay from the ADATE207 drive to compare pins, in
units of 2.5 ns. The maximum delay is 80 ns (value = 31) and the minimum delay is 2.5 ns (value = 0).

Name: T0 Alignment Pipeline Depth
Address: 0x1B
Type: Read/Write

Position Description Reset State
Bits[15:05] Not Used. 0x000
Bits[04:00]
T0 Alignment Pipeline Depth. This pipeline value matches the edge generation delay for compare
edges thereby correctly aligning compare fails and DUT data to the T0 pipeline. It should be
programmed no higher than 30 and ≥ 10.5+ RTD/4.

TMU Channel Select
This register selects one of four channels to independently direct to the TMU arm, start, and stop buses.
