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 32
shows the 16 possible control codes and the corresponding operation on the analog port.
