I/O DESCRIPTION JTCK 53 I Test clock. JTCK is used to clock state information and test data into and out of the device during operation of the TAP. This terminal should be pulled up to terminal 48 if the JTAG interface is not used. JTDI 49 I Test data input. JTDI is used to serially shift test data and test instructions into the device during operation of the TAP. This terminal should be pulled up to terminal 48 if the JTAG interface is not used. JTDO 51 O Test data output. JTDO is used to serially shift test data and test instructions out of the device during operation of the TAP. JTMS 52 I Test mode select. JTMS controls the operating state of JTAG. This terminal should be pulled up to terminal 48 if the JTAG interface is not used. JTRST 54 I Test reset. JTRST is used for asynchronous reset of the JTAG controller. This terminal should be tied to GND if not used. LED interface TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION LACTIVE 67 O LED activity indicator. LACTIVE indicates that the selected PHY is transmitting or receiving data. This signal is low for even-numbered (0, 2, 4, 6) ports and high for odd-numbered (1, 3, 5, 7) ports. LDUPCOL 66 O LED duplex/collision indicator. This LED status terminal has different meaning when in full- or half-duplex mode. In full-duplex mode, LDUPCOL is continuously driven active. In half-duplex mode, it is driven active for 20 ms after a collision. LDUPCOL indicates full-duplex mode and collisions for the currently selected PHY. This signal is active low for even (0, 2, 4, 6) ports and active high for odd (1, 3, 5, 7) ports. LLINK 68 O LED link indicator. LLINK indicates that the selected PHY has established a network link. This signal is low for even (0, 2, 4, 6) ports and high for odd (1, 3, 5, 7) ports. LSEL0, 1 64 O LED select PHY 0, 1. LED select indicator for PHY0 or PHY1, depends on polarity. This signal is high for PHY0 and low for PHY1. LSEL2, 3 63 O LED select PHY 2,3. LED select indicator for PHY2 or PHY3, depends on polarity. This signal is high for PHY2 and low for PHY3. LSEL4, 5 62 O LED select PHY 4,5. LED select indicator for PHY4 or PHY5, depends on polarity. This signal is high for PHY4 and low for PHY5. LSEL6, 7 61 O LED select PHY 6,7. LED select indicator for PHY6 or PHY7, depends on polarity. This signal is high for PHY6 and low for PHY7. |
