SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
___
The INT3 interrupt can function as the key input interrupt by setting
___
bits 7 and 6 of the INT3 interrupt control register. The key input inter-
__
rupt uses inputs KI3 to KI0 or inputs KI4 to KI0. 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 INT3/key input interrupt input circuit block diagram.
___
When the INT3 interrupt control register’s bit 7 is “0” and its bit 6 is
___
“0”, a signal from the INT3 pin is connected to the INT3 interrupt con-
___
trol circuit and INT3 external interrupt is normally performed.
___
When the INT3 interrupt control register’s bit 7 is “1” and its bit 6 is
__
“0”, signals from the KI3 to KI0 pins, which correspond to ports P57 to
P54, are inverted and then the logical sum of these signals is con-
___
nected to the INT3 interrupt control circuit. In this case, the external
__
interrupt which uses the KI3 to KI0 pins is performed.
___
When the INT3 interrupt control register’s bit 7 is “1” and its bit 6 is
__
“1”, signals from the KI4 pin, which corresponds to port P95, KI3 to
__
KI0 pins, which correspond to ports P57 to P54, are inverted and then
___
the logical sum of these signals is connected to the INT3 interrupt
__
control circuit. In this case, the external interrupt which uses the KI4
__
to KI0 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 INT3 interrupt
control register so that an interrupt request can occur by inputting “L”
__
to each of the KI3 to KI0 pins or the KI4 to KI0 pins. The interrupt vec-
___
tor is common to the INT3 interrupt’s one. Additionally, pull-up resis-
__
tor (transistors) can be added to the KI4 to KI0 pins by setting the
contents 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.
