INTERRUPTS
Interrupts occur by sixteen sources: seven external, eight internal,
and one software.
Interrupt control
Each interrupt is controlled by an interrupt request bit, an interrupt
enable bit, and the interrupt disable flag except for the software in-
terrupt set by the BRK instruction. An interrupt occurs if the corre-
sponding interrupt request and enable bits are “1” and the inter-
rupt disable flag is “0”.
Interrupt enable bits can be set or cleared by software.
Interrupt request bits can be cleared by software, but cannot be
set by software.
The BRK instruction cannot be disabled with any flag or bit. The I
(interrupt disable) flag disables all interrupts except the BRK in-
struction interrupt.
Interrupt operation
When an interrupt is received, the contents of the program counter
and processor status register are automatically stored into the
stack. The interrupt disable flag is set to inhibit other interrupts
from interfering.The corresponding interrupt request bit is cleared
and the interrupt jump destination address is read from the vector
table into the program counter.
Notes on use
When the active edge of an external interrupt (INT0 to INT4,
CNTR0, or CNTR1) is changed, the corresponding interrupt re-
quest bit may also be set. Therefore, please take following se-
quence;
(1) Disable the external interrupt which is selected.
(2) Change the active edge selection.
(3) Clear the interrupt request bit which is selected to “0”.
(4) Enable the external interrupt which is selected.
