PCI 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

PCI Bus Grant (bus master mode)

Memory Clock In (~EXCKEN = 0) or LVDSCLK Out (~ESCKEN = 1), LVDSCLK is a free running clock
which can be used to drive LVDS transmitter for DSTN panels.
External Clock Enable. Select external VCLK form CKIN and MCLK from MCKIN.
