DS3161/DS3162/DS3163/DS3164
8 PIN DESCRIPTIONS
Note: In JTAG mode, all digital pins are bidirectional to increase the effectiveness of board level ATPG patterns for
isolation of interconnect failures.
8.1 Short Pin Descriptions
Table 8-1. DS3164 Short Pin Descriptions
n = 1,2,3,4 (port number); Ipu (input with pullup); Oz (output tri-stateable, needs an external pullup or pulldown resistor to keep from floating);
Oa (analog output); Ia (analog input); I/O (bidirectional inout); all unused input pins without pullup should be tied low.
