There are four 64-pin EIA E700 AAAB SMT connectors (P11, P12, P13,
and P14) on the PrPMC750 to provide the 32/64-bit PCI interface and
optional I/O interface to the host board. The P14 connector provides an
interface to the Bank B FLASH and I2C bus along with a secondary
interface to the serial port and the JTAG/COP port. The pin assignments
