control means, under control of control software, for reading and writing to said interrupt register for storing and deleting, under software control, said hardware interrupt request in said interrupt register;
3 4 Freescale Semiconductor Overview — Programmable highest priority request — Six groups of interrupts with programmable priority — External and internal interrupts directed to host processor — Unique vector number for each interrupt source • Enhanced secure digital host controller (eSDHC) — ...
PIC Peripherals: Timers Available in all PICs. 14+ bit cores may generate interrupts on timer overflow. Some 8 bits, some 16 bits, some have prescalers Can use external pins as clock in/clock out (ie, for counting events or using a different Fosc) Warning: some peripherals share Timer re...
One-shot clock and square-wave clock One-shot clock: controlled by OS software Square-wave clock: generate periodic signal Clock tick: periodic interrupts Operating System CITS, NanKai University 18 Operating System CITS, NanKai University 19 ...
The software toolchain utilized in Dracon is based on the use of free tools, and thus not dependent on any manufacturer. Software developed for Dracon is portable, and it can run on the platform independently of the hardware device used for its implementation. This leads to saving time and co...
