SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
The INT
3
interrupt can function as the key input interrupt by setting
bits 7 and 6 of the INT
3
interrupt control register. The key input inter-
rupt uses inputs KI
3
to KI
0
or inputs KI
4
to KI
0
. Figure 10 shows the
interrupt control register bit configuration. Figure 15 shows the par-
ticular function select register 1 bit configuration, and Figure 16
shows the INT
3
/key input interrupt input circuit block diagram.
When the INT
3
interrupt control register’s bit 7 is “0” and its bit 6 is
“0”, a signal from the INT
3
pin is connected to the INT
3
interrupt con-
trol circuit and INT
3
external interrupt is normally performed.
When the INT
3
interrupt control register’s bit 7 is “1” and its bit 6 is
“0”, signals from the KI
3
to KI
0
pins, which correspond to ports P5
7
to
P5
4
, are inverted and then the logical sum of these signals is con-
nected to the INT
3
interrupt control circuit. In this case, the external
interrupt which uses the KI
3
to KI
0
pins is performed.
When the INT
3
interrupt control register’s bit 7 is “1” and its bit 6 is
“1”, signals from the KI
4
pin, which corresponds to port P8
0
, KI
3
to
KI
0
pins, which correspond to ports P5
7
to P5
4
, are inverted and then
the logical sum of these signals is connected to the INT
3
interrupt
control circuit. In this case, the external interrupt which uses the KI
4
to KI
0
pins is performed.
When using the above key input interrupt, select the edge sense
which uses the falling edge from “H” to “L” with the INT
3
interrupt con-
trol register so that an interrupt request can occur by inputting “L” to
each of the KI
3
to KI
0
pins or the KI
4
to KI
0
pins. The interrupt vector
is common to the INT
3
interrupt’s one. Additionally, pull-up resistor
(transistors) can be added to the KI
4
to KI
0
pins by setting the con-
tents of the particular function select register 1’s bits 7 and 6 and
setting “0” to each bit of the corresponding port’s direction register.
