DESCRIPTION
The use of the CMFP in a system can significantly reduce chip count, thereby reducing system cost. 1/42 September 1992 TS68HC901 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 common to most microprocessor-based systems. The resources available to the user include: Eight Individually Programmable I/O Pins with Interrupt Capability 16-Source Interrupt Controller with Individual Source Enabling and Masking Four Timers, Two of which are Multi-Mode Timers Figure 1: TS68HC901 Block Diagram . . . . . Timers may be used as Baud Rate Gener...
