cycle steal and interrupt request common poll bus.The storage and input/output devices communicate with and are controlled by the central processing unit over a looped, or unidirectional bus and control channel including a bus in, a bus out, an address and control bus, and a plurality of ...
Remember that on the 6502, the stack grows down toward $100, and the stack pointer register S is decremented immediately after each byte is written onto the stack, regardless of which instruction or interrupt condition is producing the stack pushes. For example, if stack pointer register S cont...
Interrupts, Traps, and Exceptions Chapter 17 The concept of an interrupt is something that has expanded in scope over the years. The 80x86 family has only added to the confusion surrounding interrupts by introducing the int (software interrupt) instruction. Indeed, different manufacturers have used...

Equipped with fast instruction execution time which has 20 (out of total 89) instructions that execute in a single cycle, powerful mathematical instructions and frequently used instructions (MOV, ADD, SUB, JMP) that are just 1-byte long, interrupt latency incurred by R8C MCUs is minimal. MR8C...

7.If the Timer has to run again and again, it is required to reload initial values within the routine itself (in case of mode 0 and 1). Otherwise after one cycle timer will start counting from 0000H. Example code Timer interrupt to blink an LED; Time delay in mode1 using interrupt ...
