This signal is negated on leading nRD, nWR if necessary. Configuration 1- Structure And Bit Definition Receive FLP t 58 c. Mask – Structure and Bit De Indicates a code error detected by pulldown PHY.

Maximum Guaranteed Ratings Dc Electrical Characteristics Chapter 7 Functional Description It also determines the value of the transmit and receive interrupts as a function of the queues.

Bank dataseet – Configuration Register Bank 2 – Fifo Ports Register Chapter 14 Timing Diagrams Clock And Data Recovery This bit defaults low to normal operation. Host interface however, will still be active allowing the Host access to the device through Standard IO access. The first 3 received packets must be discarded after the correction of a reverse polarity condition. Enter text from picture: Page – Figure AutoNegotiation uses a burst of link pulses, called fast link pulses and referred to as FLP’S, to pass up to 16 bits of signaling data back and forth between the LAN91C and a remote device.


Transmit pages are released by transmit completion. Configuration 2 – Structure If a packet is queued, a preamble and SFD will be transmitted.

Details of pin 1 identifier are optional but must be located within the zone indicated. Chapter 6 Signal Description Parameters Used by the LAN91C to discard the packet being received.
