I am new to working assembly code and I am trying to make a program that will read in values from ROM and depending on what values they are play a certain note for a certain length of time. The code itself compiles just fine, but when I go to send the code to the 8051, nothing happens.

These include an advance AES encryption interrupt, battery supply monitor interrupt, and an ADC conversion … WebRefer to the chapter explaining assembler programming for an explanation about interrupt routines written solely in assembler language. Catch-all interrupt vector If an unexpected interrupt occurs (interrupt is enabled and no handler is installed, which usually indicates a bug), then the default action is to reset the device by jumping to the reset vector.
WebAn interrupt is the automatic transfer of software execution in response to a hardware event that is asynchronous with the current software execution.This hardware event is called a trigger.The hardware event can either be a busy to ready transition in an external I/O device (like the UART input/output) or an internal event (like bus fault, memory fault, or a … Web1) The digits of your ID must not be directly visible in their proper order in the assembly language code!
