DESCRIPTION

The MK68901 MFP (Multi-Function Peripheral) is a

combination of many of the necessary peripheral

functions in a microprocessor system.

Included are :

Eight parallel I/O lines

Interrrupt controller for 16 sources

Four timers

Single channel full duplex USART

The use of the MFP in a system can significantly re-

duce chip count, thereby reducing system cost. The

MFP is completely 68000 bus compatible, and 24 di-

rectly addressable internal registers provide the ne-

MFP
