TS68HC901
DESCRIPTION
The use of the CMFP in a system can significantly reduce chip count, thereby reducing system cost. The CMFP is pletely 68000 bus patible, and 24 directly addressable internal registers provide the necessary control and status interface to the programmer. The CMFP is a derivative of the MK3801 STI, a Z80 family peripheral.

INTRODUCTION The TS68HC901 multi-function peripheral (CMFP) is a member of the 68000 peripherals. The CMFP directly interfaces to the 68000 processor via an asynchronous bus structure. Both vectored and polled interrupt schemes are supported, with the CMFP providing unique vector number generation for each of its 16 interrupt sources. Additionally, handshake lines are provided to facilitate DMAC interfacing. Refer to block diagram of the TS68HC901. The TS68HC901 performs many of the functions mon to most microprocessor-based systems. The resources available to the user include: Eight Individually Programmable I/O Pins with...
