1) The PLL base clock generator , CF, RC and crystal oscillators automatically stop operation.
2) There are four ways of resetting the HOLD mode.
(1) Setting the reset pin to the lower 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 bus active interrupt source established in the USB interface circuit
 X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except for reception
of a remote control signal.
1) The PLL base clock generator, CF and RC oscillator automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are six ways of resetting the X'tal HOLD mode.

Power Pin Treatment
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.
Example 1: When the microcontroller is in the backup state in the HOLD mode, the power to sustain the high level of
output ports is supplied by their backup capacitors.

USB Reference Power Option
When a voltage 4.4 to 5.5V is supplied to VDD1 and the internal USB reference voltage circuit is activated, the
reference voltage for USB port output is generated. The active/inactive state of reference voltage circuit can be switched
by the option select. The procedure for marking the option selection is described below.

When the USB reference voltage circuit is made inactive, the level of the reference voltage for USB port output is
equal to VDD1.
Selection (2) or (3) can be used to set the reference voltage circuit inactive in HOLD or HALT mode.
When the reference voltage circuit is activated, the current drain increase by approximately 100A compared with
when the reference voltage circuit is inactive.
Example 1: VDD1=VDD2=3.3V
Inactivating the reference voltage circuit (selection (4)).
Connecting VDD3 to VDD1 and VDD2.

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 VDD
goes above the operating voltage lower limit (see Figure 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 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.
