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 MX98715A 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 MX98715A 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 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.
