78 / 433 page  www.national.com 78 Revision 3.0 Signal Definitions (Continued) 2.4.19 Test and Measurement Interface Signals Signal Name Ball No. Type Description Mux EBGA TEPBGA PLL6B C28 AG4 I/O PLL6, PLL5 and PLL2 Bypass. These sig- nals are used for internal testing only. For normal operation leave unconnected. TEST1 PLL5B B29 AJ1 I/O TEST2 PLL2B D28 AH3 I/O TEST0 GXCLK AL16 V30 O GX Clock. This signal is for internal testing only. For normal operation either program as FP_VDD_ON or leave unconnected. FP_VDD_ON+ TEST3 TEST3 AL16 V30 O Internal Test Signals. These signals are used for internal testing only. For normal operation, leave unconnected unless pro- grammed as one of their muxed options. FP_VDD_ON+ GXCLK TEST2 B29 AJ1 O PLL5B TEST1 C28 AG4 O PLL6B TEST0 D28 AH3 O PLL2B GTEST AL5 F30 I Global Test. This signal is used for internal testing only. For normal operation this signal should be pulleddownwith1.5 K Ω. --- SDTEST5 AH3 D28 O Memory Internal Test Signals. These sig- nals are used for internal testing only. For normal operation, these signals should be programmed as one of their muxed options.
