Interrupts

• 28 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) 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 the remote control receiver circuit.

2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.

shortening the backup time.

Make sure that the port outputs are held at the low level in the HOLD backup mode.

goes above the operating voltage lower limit (see Fig. 4).

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the

instruction for starting the subclock oscillation circuit is executed and to the time interval that is required for the

oscillation to get stabilized after the HOLD mode is reset (see Fig. 4).

Note: The components that are involved in oscillation should be placed as close to the IC and to one another as possible

because they are vulnerable to the influences of the circuit pattern.
