INTERRUPTS
Table 3 shows the interrupt sources and the corresponding interrupt
vector addresses. Reset is also handled as an interrupt source in
this section, too.
DBC and BRK instruction are interrupts used only for debugging.
Therefore, do not use these interrupts.
Interrupts other than reset, watchdog timer, zero divide, and address
matching detection all have interrupt control registers. Table 4 shows
the addresses of the interrupt control registers and Figure 13 shows
the bit configuration of the interrupt control register.
The interrupt request bit is automatically cleared by the hardware
during reset or when processing an interrupt. Also, interrupt request
bits except for that of a watchdog timer interrupt can be cleared by
software.
An INT
i
(i = 0 to 7) interrupt request is generated by an external in-
put.
INT
i
is an external interrupt; whether to cause an interrupt at the in-
put level (level sense) or at the edge (edge sense) can be selected
with the level/edge select bit. Furthermore, the polarity of the inter-
rupt input can be selected with the polarity select bit.
When using the following pins as external interrupt input pins, be
sure to clear the direction registers of the corresponding multiplexed
ports to “0”: pins P5

When the external interrupt input read register (address 95
16
), which
is shown in Figure 12, is read out, the status of pins INT
0
through
INT
7
can directly be read.
Timer and UART interrupts are described in the respective section.
The priority of interrupts when multiple interrupt requests are caused
simultaneously is partially fixed by hardware, but, it can also be ad-
justed by software as shown in Figure 14.
The hardware priority is fixed as the following:
reset > watchdog timer > other interrupts
