Message Signaled Interrupts (MSI) are a method of signaling interrupts, using special in-band messages to replace traditional out-of-band signals on dedicated interrupt lines. While message signaled interrupts are more complex to implement in a device, they have some significant advantages over pin-based out-of-band interrupt signalling, such ...
Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it vertically (one common result is switching from portrait to landscape mode). [35] The iPhone 5 is shipped with iOS 6, which was released on September 19, 2012. [34]
The Message Signaled Interrupts (MSI) feature of the PCI 2.2 and later specifications cannot be used without the local APIC being enabled. [8] Use of MSI obviates the need for an I/O APIC. Additionally, up to 224 interrupts are supported in MSI mode, and IRQ sharing is not allowed.
Every signaling system can be characterized along each of the above axes of classification. A few examples: DTMF is an in-band, channel-associated register signaling system. It is not compelled. SS7 (e.g., TUP or ISUP) is an out-of-band, common-channel signaling system that incorporates both line and register signaling.
In a computer, an interrupt request (or IRQ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead. Hardware interrupts are used to handle events such as receiving data from a modem or network card , key presses, or mouse movements.

The top and side of an iPhone 5S, externally identical to the SE (2016).From left to right, sides: wake/sleep button, silence switch, volume up, and volume down. The touchscreen on the iPhone has increased in size several times over the years, from 3.5 inches on the original iPhone to iPhone 4S, to the current 6.1 and 6.7 inches on the iPhone 14 and 14 Pro series.
