7. PIN DESCRIPTIONS
Note: All digital pins are I/O pins in JTAG mode. This feature is to increase the effectiveness of board-level ATPG
patterns to isolate interconnect failures.
7.1 Short Pin Descriptions
n = port number (1 to 12 for DS32512, 1 to 8 for DS32508, 1 to 6 for DS32506). I = input, Ipu = input with internal pullup resistor, Ipd = input with
internal pulldown resistor, Ia = analog input, I/O = bidirectional in/out, I/Opd = bidirectional in/out with internal pulldown resistor, O = output,
Oz = high-impedance output (needs an external pullup or pulldown resistor to keep the node from floating), Oa = analog output (high
impedance), P = power supply or ground. All unused input pins without pullup should be tied low. Note: All internal pullup resistors are 50k Ω tied
to approximately 2.2V DC. See Section
