Description
PCI Clock. PCICLK provides timing for all transactions
on the PCI bus. All other PCI signals are sampled on the
rising edge of PCICLK, and all timing parameters are
defined with respect to this edge.
PCI Clock Outputs. PCICLK0 and PCICLK1 provide
clock drives for the system at 33 MHz. These clocks are
asynchronous to PCI signals. There is low skew between
all outputs. One of these clock signals should be con-
nected to the PCICLK input. All PCI clock users in the
system (including PCICLK) should receive the clock with
as low a skew as possible.
Multiplexed Address and Data. A bus transaction con-
sists of an address phase in the cycle in which FRAME#
is asserted followed by one or more data phases. During
the address phase, AD[31:0] contain a physical 32-bit
address. For I/O, this is a byte address. For configuration
and memory, it is a DWORD address. During data
phases, AD[7:0] contain the least significant byte (LSB)
and AD[31:24] contain the most significant byte (MSB).
Multiplexed Command and Byte Enables. During the
address phase of a transaction when FRAME# is active,
C/BE[3:0]# define the bus command. During the data
phase, C/BE[3:0]# are used as byte enables. The byte
enables are valid for the entire data phase and determine
which byte lanes carry meaningful data. C/BE0# applies
to byte 0 (LSB) and C/BE3# applies to byte 3 (MSB).
PCI Interrupts. The SC2200 provides inputs for the
optional “level-sensitive” PCI interrupts (also known in
industry terms as PIRQx#). These interrupts can be
mapped to IRQs of the internal 8259A interrupt control-
lers using PCI Interrupt Steering Registers 1 and 2
(F0 Index 5Ch and 5Dh).
Note:
If AB1D function is selected but not used, tie
AB1D high.
If AB2C function is selected but not used, tie
AB2C high.
If AB2D function is selected but not used, tie
AB2D high.
If selected as INTC# or INTD# function(s) but not
used, tie INTC# and INTD# high.
