„Interrupts
• 40 sources, 10 vector addresses

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

Power Pin Treatment
Connect the IC as shown below to minimize the noise input to the VDD1 pin. and extend the backup period. 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 4.5 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 the reference voltage circuit can be
switched by 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 increases by approximately 100μA 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.

Characteristics of a Sample Main System Clock Oscillation Circuit
Given below are the characteristics of a sample main system clock oscillation circuit that are measured using a
SANYO-designated oscillation characteristics evaluation board and external components with circuit constant values
with which the oscillator vendor confirmed normal and stable oscillation.
Table 1 shows the characteristics of a oscillation circuit when USB host function is not used.
If USB host function is to be used, it is absolutely recommended to use an oscillator that satisfies the precision and
stability according to the USB standards.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized in the
following cases (see Figure 4):
• Till the oscillation gets stabilized after VDD goes above the operating voltage lower limit.
• Till the oscillation gets stabilized after the instruction for starting the main clock oscillation circuit is executed
• Till the oscillation gets stabilized after the HOLD mode is reset.
• Till the oscillation gets stabilized after the X'tal HOLD mode is reset with CFSTOP (OCR register, bit 0) set to 0

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized in the
following cases (see Figure 4):
• Till the oscillation gets stabilized after the instruction for starting the subclock oscillation circuit is executed
• Till the oscillation gets stabilized after the HOLD mode is reset with EXTOSC (OCR register, bit 6) set to 1
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.
