Datasheet
3.3.2
Device Identification Register (IDR)
The IDR register provides access to the manufacturer number, part number and the LXT381
revision. The register is arranged per IEEE 1149.1 and is represented in
Table 5
. Data into the IDR
is shifted in LSB first
.
3.3.3
Bypass Register (BYR)
The Bypass Register is a 1 bit register that allows direct connection between the TDI input and the
TDO output.
3.3.4
Analog Port Scan Register (ASR)
The ASR is a 5 bit shift register used to control the analog test port at pins AT1, AT2. When the
INTEST_ANALOG instruction is selected, TDI connects to the ASR input and TDO connects to
the ASR output. After 5 TCK rising edges, a 5 bit control code is loaded into the ASR. Data into
the ASR is shifted in LSB first.
Table 6
shows the 16 possible control codes and the corresponding operation on the analog port.
The Analog Test Port can be used to verify continuity across the coupling transformers primary
winding
