INTERRUPTS
Interrupts occur by 17 sources among 17 sources: seven external,
nine 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
corresponding interrupt request and enable bits are “1” and the in-
terrupt 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.
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.
sNotes
When setting the followings, the interrupt request bit may be set to
“1”.
When setting external interrupt active edge
Related register: Interrupt edge selection register (address 3A16)
I2C start/stop condition control register (address 3016)
Timer XY mode register (address 2316)
When switching interrupt sources of an interrupt vector address
where two or more interrupt sources are allocated
Related register: Interrupt edge selection register (address 3A16)
When not requiring for the interrupt occurrence synchronized with
these setting, take the following sequence.
Set the corresponding interrupt enable bit to “0” (disabled).
Set the interrupt edge select bit or the interrupt source select bit.
Set the corresponding interrupt request bit to “0” after 1 or more
instructions have been executed.
Set the corresponding interrupt enable bit to “1” (enabled).
