2.5 Interrupt Circuits

The

 

RFM

‐

5565

 

has

 

a

 

single

 

interrupt

 

output

 

(INTA#).

 

One

 

or

 

more

 

events

 

on

 

the

 

RFM

‐

5565

 

board

 

can

 

cause

 

the

 

interrupt.

 

The

 

sources

 

of

 

the

 

interrupt

 

can

 

be

 

individually

 

enabled

 

and

 

monitored

 

through

 

several

 

registers.

The

 

interrupt

 

circuitry

 

of

 

the

 

RFM

‐

5565

 

is

 

arranged

 

in

 

two

 

tiers.

 

The

 

primary

 

tier

 

of

 

interrupts

 

is

 

enabled

 

and

 

monitored

 

by

 

the

 

Local

 

Configuration

 

Register’s

 

INTCSR

  

at

 

offset

 

$68.

 

The

 

sources

 

for

 

monitoring

 

the

 

primary

 

tier

 

interrupts

 

include:

1.

 

DMA

 

Ch

2.

 

Local

 

Interrupt

 

Input

 

(LINTi#)

      

The

 

primary

 

tier

 

interrupt

 

source

 

(1)

 

is

 

used

 

during

 

DMA

 

cycles

 

and

 

must

 

be

 

configured

 

in

 

the

 

DMA

 

registers.

The

 

other

 

primary

 

tier

 

interrupt

 

source

 

(2)

 

is

 

the

 

Local

 

Interrupt

 

Input

 

(LINTi#).

 

All

 

secondary

 

tier

 

interrupts

 

are

 

funneled

 

through

 

the

 

LINTi#.

 

Second

 

tier

 

interrupts

 

include

 

several

 

operational

 

status

 

bits,

 

faults,

 

and

 

network

 

interrupts.

 

The

 

second

 

tier

 

interrupts

 

are

 

selected

 

and

 

monitored

 

through

 

the

 

two
