PGE Ethernet Controller: Media Independent Interface (MII) (continued) Terminal Signal Default Pull Type Description Type Pull State Signal Name 144 PGE N2HET1[10]/MII_TX_CLK/MII_TX_AVCLK4 118 I/O Pull Down - MII output transmit clock N2HET1[10]/MII_TX_CLK/MII_TX_AVCLK4 118 Transmit clock MIBSPI5SOMI[0]/MII_TXD[0] 98 Output Pull Up - Transmit data MIBSPI5SIMO[0]/MII_TXD[1] 99 MIBSPI1NCS[0]/MIBSPI1SOMI[1]/MII_TXD[2] 105 N2HET1[08]/MIBSPI1SIMO[1]/MII_TXD[3] 106 Pull Down - MIBSPI5CLK/MII_TXEN 100 Pull Up - Transmit enable 2.4.1.12 System Module Interface Table 2-16. PGE System Module Interface Terminal Signal Default Pull Type Description Type Pull State Signal Name 144 PGE nPORRST 46 Input Pull Down 100uA Power-on reset, cold reset External power supply monitor circuitry must drive nPORRST low when any of the supplies to the microcontroller fall out of thespecified range. This terminal has a glitch filter. See Section 4.8. nRST 116 I/O Pull Up 100uA System reset, warm reset, bidirectional. The internal circuitry indicates any reset condition by driving nRST low. The external circuitry can assert a system reset by driving nRST low. To ensure that an external reset is not arbitrarily generated, TI recommends that an external pull-up resistor is connected to this terminal. This terminal has a glitch filter. See Section 4.8. nERROR 117 I/O Pull Down 20uA ESM Error Signal Indicates error of high severity. See Section 4.18.
