Interrupt Source Flags
•
31 sources, 10 vector addresses
1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt requests
of the level equal to or lower than the current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest
level takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest
vector address takes precedence.

2) There are three ways of resetting the HOLD mode.
(1) Setting the reset pin to the low level
(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
(3) Having an interrupt source established at port 0
•
X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer
and infrared remote controller circuit.

2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are five ways of resetting the X'tal HOLD mode.
(1) Setting the reset pin to the low level
(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
