MFP Configuration via GMODE Register, Bit Field ’PERCFG’:
Peripheral Block Configuration
The peripheral block basically consists of the functions
• Local Bus Interface (LBI)
• General Purpose Port (GPP)
• Synchronous Serial Controller (SSC)
which can be operated in various combinations/configurations.
Bit field ’PERCFG’ selects the peripheral configuration and switches the
multiplexed signal pins accordingly:
PCI Interface Mode (DEMUX pin connected to V
