16 / 174 page  1.0 Signal/Pin Connection and Description (Continued) 16 www.national.com Revision 1.1 1.4 DETAILED SIGNAL/PIN DESCRIPTIONS This section describes all signals of the PC87373 device. The signals are organized by functional group. 1.4.1 LPC Interface Signal Pin(s) I/O Buffer Type Power Well Description LAD3-0 57,59 61,62 I/O INPCI/OPCI VDD3 LPC Address-Data. Multiplexed command, address bi-directional data and cycle status. PCI_CLK 55 I INPCI VDD3 LPC Clock. PCI clock used for the LPC bus (up to 33 MHz). LFRAME 56 I INPCI VDD3 LPC Frame. Low pulse indicates the beginning of a new LPC cycle or termination of a broken cycle. LDRQ 54 O OPCI VDD3 LPC DMA Request. Encoded DMA request for LPC interface. PCI_RESET 63 I INPCI VDD3 LPC Reset. PCI system reset used for the LPC bus (Hardware Reset). SER_IRQ 53 I/O INPCI/OPCI VDD3 Serial IRQ. The interrupt requests are serialized over a single pin, where each IRQ level is delivered during a designated time slot. LPCPD 52 I INPCI VDD3 Power Down. Indicates that power to the LPC interface is about to be turned off. When LPCPD functionality is not required, an internal pull-up resistor allows this pin to be left floating. PCIRST_OUT 73 O O14/14 VSB3 PCI Reset Output. PCI system reset. PCIRST_OUT is a buffered copy of PCI_RESET when VDD3 is on, and it is held at low level when VDD3 is off. PCIRST_OUT2 74 O O14/14 VSB3 PCI Reset Output 2. PCI system reset (same behavior as PCIRST_OUT above). IDE_RSTDRV64 O OD6 VDD3 IDE Reset Output. IDE drive reset. IDE_RSTDRV is a buffered copy of PCI_RESET when VDD3 is on, and it is floating when VDD3 is off. |
