INTERRUPTS
Table 1 shows the interrupt types and the corresponding interrupt
vector addresses. Reset is also treated as a type of interrupt and
____
is discussed in this section, too. DBC is an interrupt used during
debugging.
____
Interrupts other than reset, DBC, watchdog timer, zero divide, and
BRK instruction all have interrupt control registers. Table 2 shows
the addresses of the interrupt control registers and Figure 6 shows
the bit configuration of the interrupt control register.
Use the SEB and CLB instructions when setting each interrupt
control register.
The interrupt request bit is automatically cleared by the hardware
during reset or when processing an interrupt.
____
Also, interrupt request bits other than DBC and watchdog timer
can be cleared by software.
____
INT2 to INT0 are external interrupts and whether to cause an inter-
rupt at the input level (level sense) or at the edge (edge sense)
can be selected with the level sense/edge sense selection bit. Fur-
thermore, the polarity of the interrupt input can be selected with
polarity selection bit.
Timer and UART interrupts are described in the respective sec-
tion. The priority of interrupts when multiple interrupts are caused
simultaneously is partially fixed by hardware, but, it can also be
adjusted by software as shown in Figure 7. The hardware priority
is fixed the following:
____
reset > DBC > watchdog timer > other interrupts
Interrupts
A-D conversion
UART1 transmit
UART1 receive
UART0 transmit
UART0 receive
Timer B2
Timer B1
Timer B0
Timer A4
Timer A3
Timer A2
Timer A1
Timer A0
____
INT2 external interrupt
____
INT1 external interrupt
____
INT0 external interrupt
Watchdog timer
____
DBC (unusable)
Break instruction
Zero divide
Reset
