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

• Conversion time calculation method: TCAD8= ((32/(AD division ratio))+2) × tCYC
Note 6-1: The quantization error (±1/2LSB) is excluded from the absolute accuracy.
Note 6-2: The conversion time refers to the interval from the time a conversion starting instruction is issued till the time
the complete digital value against the analog input value is loaded in the result register.
The conversion time is twice the normal value when one of the following conditions occurs:
• The first AD conversion is executed in the 12-bit AD conversion mode after a system reset.
• The first AD conversion is executed after the AD conversion mode is switched from 8-bit to 12-bit AD
conversion mode.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after VDD
exceeds its lower limit operating voltage (see Figure 4).

Characteristics of a Sample Subsystem Clock Oscillation Circuit
Given below are the characteristics of a sample subsystem clock oscillation circuit that are measured using a Our
designated oscillation characteristics evaluation board and external components with circuit constant values with which
the oscillator vendor confirmed normal and stable oscillation.

Remarks
CL=12.5pF (*3)
Normal XT mode
CL=4.4pF(*4)
Low power XT mode
(*1) Normal XT mode (*3) or low power XT mode (*4) should be selected for the sub-system clock oscillator circuit.
(*2) Contact Seiko Instruments, Inc., (http://www.sii-crystal.com) for further information about the use of the
resonator.
(*3) When considering the use of normal XT mode, use an resonator that has a large load capacitance.
(*4) When considering the use of low power XT mode, use a resonator that has a small load capacitance. The
applicable CL value of 4.4pF makes it possible to achieve a high time accuracy for the subclock oscillator as well
as high-speed oscillation startup and low power dissipation. In addition to this value, 6.0pF and 7.0pF also fall
within the applicable CL value range.
(*5) A sample PCB trace pattern for a Seiko Instrument resonator is shown below.
(Note 1) The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized
after an instruction for starting the subclock oscillator circuit is issued or the time interval that is required for
the oscillation to get stabilized after the HOLD mode is released (see Figure 4).
(Note 2) The circuit constants shown are the reference values that are provided by the resonator vendor for evaluation.
To make final verification of the oscillation characteristics on production boards, call the resonator vendor for
evaluation on printed circuit boards.
(Note 3) When using an oscillator circuit, observe the following wiring precautions to avoid the possible adverse
influence of wiring capacitance, especially in low power XT mode:
• Place the components that are involved in oscillation as close to the resonator as possible with the shortest
possible traces as the oscillation characteristics are subject to the variation of trace patterns.
• Do not take a signal directly from the oscillator circuit.
• Do not place the oscillator circuit in the vicinity of any lines that carry large current.
• Exercise extreme care in the wiring method when using low power XT mode.

Note: The oscillation frequency of any RC oscillator using OSC1 or OSC0 varies according to the printed circuit
patterns and components mounted on the board. It also varies greatly according to the shape and form of the
product (chip, plastic package, etc.) and board capacitance. Consequently, the characteristics charts given below
should be used merely as reference values and the resistance value be determined after evaluating them with the
actual product.
