 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

level takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest
vector address takes precedence.

*1: Connect the IC as shown below to minimize the noise input to the VDD1 pin.
Be sure to electrically short the VSS1, VSS2, and VSS3 pins.
*2: The internal memory is sustained by VDD1. If none of VDD2 and VDD3 are backed up, the high level output at
the ports are unstable in the HOLD backup mode, allowing through current to flow into the input buffer and thus
shortening the backup time.
Make sure that the port outputs are held at the low level in the HOLD backup mode.

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.
