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.
No.

Standby Function
HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation
(Some parts of the serial transfer function stop operation) .
1) Oscillation is not stopped automatically.
2) Canceled by a system reset or occurrence of an interrupt
HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The CF, RC, X’tal, and multifrequency RC oscillators automatically stop operation.
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.
1) The CF, RC, and multifrequency RC oscillators automatically stop operation.
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
(3) Having an interrupt source established at port 0
(4) Having an interrupt source established in the base timer circuit
(5) Having an interrupt source established in the infrared remote control receiver circuit

Note 6-1: The quantization error (±1/2LSB) must be excluded from the absolute accuracy. The absolute accuracy must
be measured in the microcontroller's state in which no I/O operations occur at the pins adjacent to the analog
input channel.
Note 6-2: The conversion time refers to the period from the time an instruction for starting a conversion process till the
time the conversion results register(s) are loaded with a complete digital conversion value corresponding to
the analog input value.
The conversion time is 2 times the normal-time conversion time when:
• The first AD conversion is performed in the 12-bit AD conversion mode after a system reset.
• The first AD conversion is performed after the AD conversion mode is switched from 8-bit to 12-bit
conversion mode.

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).
Caution: 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.
