160 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 MX98725 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 MX98725
that access to the bus is granted
Power Management Event: asserts low when Magic Packet is received.
Start externel circuit signal: asserts low to enable system's power
supply when Magic Packet is detected. Normally tri-stated.
LAN wake up signal: asserts high to indicate a magic packet has been
detected in Magic Packet enable mode.
Enable On-Chip Power-On-Reset : normally unconnected.
Boot PROM address bit 1(EECS=0): together with BPA[17:0] 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[17:0] to access
external boot PROM or FLASH up to 256KB.
EEPROM clock(EECS=1): EEPROM clock input pin
Boot PROM address lines:
Boot PROM data line 0(EECS=0): boot ROM or flash data line 0.
(EEPROM data out(EECS=1): EEPROM serial data out pin(during
reset initialization.)
Boot PROM data lines: boot ROM or FLASH data lines 7-0.
EEPROM chip select.
FLASH Write Enable
FLASH ROM Output Enable
FLASH Chip Select pin
