Interrupts
• 12 sources, 11 vector addresses
1) Provides three levels 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.

Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.

2) Released by a system reset or occurrence of an interrupt.
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) OSC1, internal RC and X’tal oscillators automatically stop operation.
2) There are the following methods of resetting the HOLD.
(1) Setting the reset pin to the low level
(2) Having an interrupt source established in the SIO0
(3) Having an interrupt source established in the UART2
(4) Having an interrupt source established in the P00 to P05
(5) Having an interrupt source established in the SEG71 to SEG64
• X’tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except using OSC0.

Note 1-1: The mean output current is a mean value measured over 100ms.
Note: We assume that the measurements for the allowable operating ranges and electrical characteristics described in
this document are performed with the chip mounted in a package.
Although this product is shipped in chip form, the characteristic values listed in this document are measured with
this IC mounted on a Our designated package at operating ambient temperature range of -20°C to +70°C.
The specifications of this product in package form or in chip forms are basically identical, however, the
characteristics of the product in chip form may vary depending on the board on which the product is mounted, the
bonding pressure, and the type of mold resin used.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Note 7-1: 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 7-2: 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
following reference timing points: (See Figure 4)
• VDD goes above the operating voltage lower limit.
• An instruction for starting the OSC1 clock oscillator circuit is executed.
• Oscillation starts after the microcontroller exits the X'tal HOLD mode with the ENOSC1 bit (OCR0 register, bit 1)
set to 1.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the
instruction for starting the OSC0 clock oscillation circuit is executed. (See Figure 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.

Note: The oscillation frequency changes with the board pattern and used parts when OSC1 and OSC0 are used as the
RC oscillation. It also greatly depends on the product shape (chip and plastic package) and the board capacitance,
and it is recommended to evaluate the resistor value with an actual product. Use the following characteristics as
