... ICs. The application system designer finds it dif- ficult to use them in small- and medium-sized application products in terms of cost as well as functional complexity. The LC8953 (Programmable Universal Peripheral/Port Expansion uniT) has optimized on-chip control circuits enabling the 68000 MPU to control the LC8951 (RCHIP) and LC8955 ...

... MPU and the LC8955. This in- terface enables direct communication between them result, data can be directly read from or written to internal registers of the LC8955 from the MPU. LC8953 TICKGEN (Tick Generator) The TICKGEN functional block is used to generate timer interrupt clocks for a real-time operating system. The timer interrupt clocks can be generated by dividing the system clock or selecting an external input clock ...
