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 49
Device Identification Register (IDR)
The IDR register provides access to the manufacturer number, part number and the LXT385
ransceiver revision. The register is arranged per IEEE 1149.1 and is represented in
into the IDR is shifted in LSB first.
Bypass Register (BYR)
The Bypass Register is a 1 bit register that allows direct connection between the TDI input and the
TDO output.
