The following signals for the PCI interface are available on connector P14.

GPIOx: GENERAL PURPOSE INPUT OUTPUT These I/O signals (TTL) are connected to MV64460 MPP[19, 21:27]. At powerup (default), these pins are configured as inputs.

LPa_DX+/-,LPb_DX+/-:LINK PORT signals for Ethernet 10/100/1000 MDI

SERIALxTXD: SERIAL PORT 1-2 TRANSMIT DATA (Output to PMC, TTL or EIA-232)

SERIALxRXD: SERIAL PORT 1-2 RECEIVE DATA (Input to PMC, TTL or EIA-232)
