Memory Write Enable Negated Bus
Signals which bytes are to be written during a memory transaction. Bits act as Byte Enable and
mem_addr[1:0] signals for 8-bit or 16-bit wide addressing.
Memory Wait Negated
Requires external pull-up.
SRAM/IOI/IOM modes: Allows external wait-states to be injected during last cycle before data is sampled.
DPM (dual-port) mode: Allows dual-port busy signal to restart memory transaction.
Alternate function: sdram_wait_n.
Memory FCT245 Output Enable Negated
Controls output enable to optional FCT245 transceiver bank by asserting during both reads and writes to
a memory or I/O bank.
Memory FCT245 Direction Xmit/Rcv Negated
Recommend external pull-up.
Alternate function: cpu_dt_r_n. See CPU Core Specific Signals below.
Output Clock
Optional clock output.
PCI Multiplexed Address/Data Bus
Address driven by Bus Master during initial frame_n assertion, and then the Data is driven by the Bus
Master during writes; or the Data is driven by the Bus Slave during reads.
PCI Multiplexed Command/Byte Enable Bus
Command (not negated) Bus driven by the Bus Master during the initial frame_n assertion. Byte Enable
Negated Bus driven by the Bus Master during the data phase(s).
PCI Parity
Even parity of the pci_ad[31:0] bus. Driven by Bus Master during Address and Write Data phases. Driven
by the Bus Slave during the Read Data phase.
PCI Frame Negated
Driven by the Bus Master. Assertion indicates the beginning of a bus transaction. De-assertion indicates
the last datum.
PCI Target Ready Negated
Driven by the Bus Slave to indicate the current datum can complete.
PCI Initiator Ready Negated
Driven by the Bus Master to indicate that the current datum can complete.
PCI Stop Negated
Driven by the Bus Slave to terminate the current bus transaction.
PCI Initialization Device Select
Uses pci_req_n[2] pin. See the PCI subsection.
PCI Parity Error Negated
Driven by the receiving Bus Agent 2 clocks after the data is received, if a parity error occurs.
System Error
External pull-up resistor is required.
Driven by any agent to indicate an address parity error, data parity during a Special Cycle command, or
any other system error.
PCI Clock
Clock for PCI Bus transactions. Uses the rising edge for all timing references.
