Example:

Set

the

address

of

A

to

OXFFFF

and

the

®

When

A

is

used

as

a

(same

all

modules

under

For

example:

Set

the

of

A

as

or

0x0000,

and

the

as

0x04;

When

module

A

After

immediately

output

During

this

after

completion,

and

starts

to

work

normally

according

to

the

Therefore,

the
