4. Precautions and Usage Considerations Specific to Each
4.1
4.1.1
Product Group
This section describes matters specific to each product group which need to be taken into
consideration when using devices. If the same item is described in Sections 3 and 4, the
description in Section 4 takes precedence.
(1) Using resonators which are not specifically recommended for use
Resonators recommended for use with Toshiba products in microcontroller oscillator applications
are listed in Toshiba databooks along with information about oscillation conditions. If you use a
resonator not included in this list, please consult Toshiba or the resonator manufacturer
concerning the suitability of the device for your application.
(2) Undefined functions
In some microcontrollers certain instruction code values do not constitute valid processor
instructions. Also, it is possible that the values of bits in registers will become undefined. Take
care in your applications not to use invalid instructions or to let register bit values become
undefined.
(3) Scratch and puncture wounds by the point of a probe
The tips of probes and adaptors used in development tools are individually designed to be
compatible with particular devices. Probes for some devices have sharp points. When you handle
them bare-handed, take care not to suffer a scratch or puncture wound.
