The Multi Function Port consists of a set of I/O signal pins and three internal function
blocks sharing these signal pins.
The function blocks are:
• Local Bus Interface (LBI)
• Synchronous Serial Communication Interface (SSC)
• General Purpose I/O Port (GPP)
The MFP is only available in PCI bus operation mode, because in de-multiplexed bus
mode, all MFP I/O signals are used for the 32-bit address bus extension.
Various configurations allow simultaneous operation of the three function blocks:

The configuration is selected via bit field ’PERCFG’ in register GMODE. The following
table shows all supported ’PERCFG’ bit field options (also refer to
