Microelectronic Systems 3: Checkbook aims to extend the range of hardware, software, and interfacing techniques developed at level 2. This book concentrates on the highly popular 6502, Z80, and 6800 microprocessors and contains approximately 70 tested programs that may be used with little or no modification on most systems based on these microprocessors. This text also covers the main points concerned with computer hardware configuration, interfacing devices, subroutines and the stack, polling and interrupts, microelectronic stores, and address decoding and organization. Each chapter of the book contains worked problems for the respective topics. Microprocessor instruction sets for MS6502, Z80, and MC6800 are provided in the Appendix. Students taking Microelectronic Systems courses will find this book invaluable.Problem 15 The block diagram of an 8255 Programmable Peripheral Interface ( PPI) device is shown in Fig.21. Describe the three modes of operation available with this device. The 8255 PPI has three I/O ports (Port A, Port B and Port C), anbsp;...
