INTERRUPTS
Interrupts occur by thirteen sources: five external, seven 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
flag disables all interrupts except the BRK instruction interrupt.
When several interrupts occur at the same time, the interrupts are
received according to priority.
Interrupt Operation
By acceptance of an interrupt, the following operations are auto-
matically performed:
1. The contents of the program counter and the processor status
register are automatically pushed onto the stack.
2. The interrupt disable flag is set and the corresponding interrupt
request bit is cleared.
3. The interrupt jump destination address is read from the vector
table into the program counter.
s Notes on Interrupts
When the active edge of an external interrupt (INT0 , INT1, CNTR0
or CNTR1) is set or an interrupt source where several interrupt
source is assigned to the same vector address is switched, the
corresponding interrupt request bit may also be set. Therefore,
take following sequence:
(1) Disable the interrupt.
(2) Set the interrupt edge selection register (Timer X control regis-
ter for CNTR0, Timer Y mode register for CNTR1).
(3) Clear the set interrupt request bit to “0.”
(4) Enable the interrupt.
Notes1: Vector addresses contain interrupt jump destination addresses.
2: Reset function in the same way as an interrupt with the highest priority.
