OPCI multiplexed Address and Data Bus. A bus transaction consists of an address cycle followed by one or
more data cycles.
PCI Bus Command and Byte Enables. These signals carry the bus command during the address cycle and
byte enable during data cycles.
Parity. LynxEM+ asserts this signal to verify even parity across AD [31:0] and C/~BE [3:0].
Cycle Frame. LynxEM+ asserts this signal to indicate the beginning and duration of a bus transaction. It is
de-asserted during the final data cycle of a bus transaction.
Target Ready. A bus data cycle is completed when both ~IRDY and ~TRDY are asserted on the same
cycle.
Initiator Ready. A bus data cycle is completed when both ~IRDY and ~TRDY are asserted on the same
cycle.
Stop. LynxEM+ asserts this signal to indicate that the current target is requesting the master to stop current
transaction.
Device Select. LynxEM+ asserts this signal when it decodes its addresses as the target of the current
transaction.
ID Select. This input is used during PCI configuration read/write cycles.
PCI System Clock, 33 MHz.
PCI System Reset. LynxEM+ asserts this signal to force registers and state machines to initial default
values

External SGRAM Block write
External SGRAM Bank Select. SDRAM has dual internal banks. Bank address defi nes to which bank the current command is being applied.
External SGRAM clock. SDCK is driven by the memory clock. All SDRAM input signals are sampled on the positive edge of SDCK.
External SGRAM clock enable. SDCKEN activates (HIGH) and deactivates (LOW) the SDCLK signal.Deactivating the SDCK provides POWER-DOWN and SELF-REFRESH mode.

M-signal or Display Enable. This signal is used to indicate the active horizontal display time.FPR3E [7] is used to select1 = M-signal0 = Display Enable
Flat Panel Shift Clock. This is the pixel clock for Flat Panel Data.
Flat Panel Enable. This signal needs to become active after all panel voltages, clocks, and data are sup-plied. This signal also needs to become inactive before any panel voltages or control signals are removed. FPEN is part of the VESA FPDI-1B specification.
Flat Panel VDD Enable. This signal is used to control LCD logic power.
Flat Panel Voltage Bias Enable. This signal is used to control LCD Bias power.
