WebThe number of interrupts available varies from processor to processor. The .org directive In assembly code, the .org directive is used to set vector jump locations. This assembler directive (or "command", if you like) tells the assembler to set the location counter to an absolute value. It is not part of the AVR instruction set, WebInterrupts solve this problem by instead letting the device notify the CPU of an event, such as the UART receiving a new data byte. If you read the manual for the PL011 UART in the previous chapter, you probably remember seeing some registers that control interrupt settings, which we ignored at the time.
