7 / 22 page SCANSTA112 www.ti.com SNLS161I – DECEMBER 2002 – REVISED APRIL 2013 PIN DESCRIPTIONS (continued) No. Pin Name Pins I/O Description S(0-7) 8 I SLOT IDENTIFICATION: The configuration of these pins is used to identify (assign a unique address to) each 'STA112 on the system backplane OE 1 I OUTPUT ENABLE for the Local Scan Ports, active low. When high, this active-low control signal TRI-STATEs all local scan ports on the 'STA112, to enable an alternate resource to access one or more of the local scan chains. TDO(01-06) 6 O TEST DATA OUTPUTS: Individual output for each of the local scan ports . These TRI-STATE outputs have 12mA of drive current. TDI(01-06) 6 I TEST DATA INPUTS: Individual scan data input for each of the local scan ports. This input has a 25K Ω internal pull-up resistor. TMS(01-06) 6 O TEST MODE SELECT OUTPUTS: Individual output for each of the local scan ports. TMSn does not provide a pull-up resistor (which is assumed to be present on a connected TMS input, per the IEEE 1149.1 requirement) . These TRI-STATE outputs have 24mA of drive current. TCK(01-06) 6 O LOCAL TEST CLOCK OUTPUTS: Individual output for each of the local scan ports. These are buffered versions of TCKB . These TRI-STATE outputs have 24mA of drive current. TRST(01-06) 6 O LOCAL TEST RESETS: A gated version of TRSTB. These TRI-STATE outputs have 24mA of drive current. A001, A101 2 I LOCAL PASS-THROUGH INPUTS: General purpose inputs which can be driven to the backplane pin YB. (Only on LSP0 and LSP1. Only available when a single LSP is selected) . These inputs have a 25K Ω internal pull-up resistor. Y001, Y101 2 O LOCAL PASS-THROUGH OUTPUT: General purpose outputs which can be driven from the backplane pin AB. (Only on LSP0 and LSP1. Only available when a single LSP is selected) . These TRI-STATE outputs have 12mA of drive current.
