128 Pin Function and Driver
PCI bus parity bit: shared PCI bus even parity bit for 32 bits AD bus and CBE
bus.
PCI Target requested transfer stop signal: as bus master, assertion of STOPB
cause MX98715AEC-D either to retry, disconnect, or abort.
PCI bus request signal: to initiate a bus master cycle request
PCI bus grant acknowledge signal: host asserts to inform MX98715AEC-D
that access to the bus is granted
Boot PROM address bit 1(EECS=0): together with BPA[15:0] to access
external boot PROM up to 256KB.
EEPROM data in(EECS=1): EEPROM serial data input pin.
Boot PROM address bit 0(EECS=0): together with BPA[15:0] to access
external boot PROM up to 256KB.
EEPROM clock(EECS=1): EEPROM clock input pin
Boot PROM address line.
Boot PROM address line 15.
Programmable LED pin 0:
CSR9.28=1 Set the LED as Link Speed (10/100)LED.
CSR9.28=0 Set the LED as Activity LED.
Default is activity LED after reset.
<Note>:This pin acts as LED0 normally. It automatically switch to Boot
PROM address 15 function while accessing Boot PROM.
Boot PROM data line 0(EECS=0): boot PROM or flash data line 0.
EEPROM data out(EECS=1): EEPROM serial data outpin(during reset
initialization).
Boot PROM data lines: boot PROM or flash data lines 7-0.
EEPROM Chip Select pin.
Boot PROM Output Enable.
Connecting an external resistor to ground, Resistor value=510 ohms
Connecting an external resistor to ground, Resistor value=510 ohms
Connecting an external resistor to ground, Resistor value=1.5K ohms.
Not connected.
Twisted pair receive differential input: Support both 10 Base-T and 100
Base-TX receive differential input.
