This is first part of an intended series about interrupts. If you are just starting out with microcontrollers or microprocessors, you have probably written a simple program that turns an LED on and off, reads a button, or sends some text over a serial port. These programs usually follow a straight line: do this, then […]

RETI Instructions

If you spend enough time writing interrupt service routines in low-level embedded code, one tiny instruction shows up again and again: RETI. On paper it looks simple. It means RETurn from Interrupt. In practice, though, that small instruction exposes deep architectural differences between microcontroller families. On some CPUs RETI is a real instruction with distinct […]
