Interrupt Controller

10.1 Overview

The MC96F6432S supports up to 23 interrupt sources. The interrupts have separate enable register bits associated

with them, allowing software control. They can also have four levels of priority assigned to them. The non-maskable

interrupt source is always enabled with a higher priority than any other interrupt source, and is not controllable by

software. The interrupt controller has following features:

−

Receive the request from 23 interrupt source

−

6 group priority

−

4 priority levels

−

Multi Interrupt possibility

−

If the requests of different priority levels are received simultaneously, the request of higher prioritylevel is

served first.

−

Each interrupt source can be controlled by EA bit and each IEx bit

−

Interrupt latency: 3~9 machinecycles in single interrupt system

The non-maskable interrupt is always enabled. The maskable interrupts are enabled through four pair of interrupt

enable registers (IE, IE1, IE2, and IE3). Each bit of IE, IE1, IE2, IE3 register individually enables/disables the

corresponding interrupt source. Overall control is provided by bit 7 of IE (EA). When EA is set to

‘0’, all interrupts are

disabled: when EA is set to

‘1’, interrupts are individually enabled or disabled through the other bits of the interrupt

enable registers. The EA bit is always cleared to

‘0’ jumping to an interrupt service vector and set to ‘1’ executing the

[RETI] instruction. The MC96F6432S supports a four-level priority scheme. Each maskable interrupt is individually

assigned to one of four priority levels according to IP and IP1.

Default interrupt mode is level-trigger mode basically, but if needed, it is possible to change to edge-trigger mode.

Table 10-1 shows the Interrupt Group Priority Level that is available for sharing interrupt priority. Priority of a group is

set by two bits of interrupt priority registers (one bit from IP, another one from IP1). Interrupt service routine serves

higher priority interrupt first. If two requests of different priority levels are received simultaneously, the request of higher

priority level is served prior to the lower one.
