INTERRUPTS
Interrupts can be caused by 12 different sources consisting of 3 ex-
ternal, 7 internal, 1 software, and reset.
Interrupts are vectored interrupts with priorities shown in Table 1. Re-
set is also included in the table because its operation is similar to an
interrupt.
When an interrupt is accepted, the registers are pushed, interrupt
disable flag I is set, and the program jumps to the address specified
in the vector table. The interrupt request bit is cleared automatically.
The reset can never be disabled. Other interrupts are disabled when
the interrupt disable flag is set.

All interrupts except the BRK instruction interrupt have an interrupt
request bit and an interrupt enable bit. The interrupt request bits are
in interrupt request registers 1 and 2 and the interrupt enable bits are
in interrupt control registers 1 and 2. Figure 4 shows the structure of
the interrupt request registers 1 and 2 and interrupt control registers
1 and 2.
Interrupts other than the BRK instruction interrupt and reset are ac-
cepted when the interrupt enable bit is “1”, interrupt request bit is “1”,
and the interrupt disable flag is “0”. The interrupt request bit can be
reset with a program, but not set. The interrupt enable bit can be set
and reset with a program.
Reset is treated as a non-maskable interrupt with the highest priority.
Figure 5 shows interrupts control.
