4.1.1
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.
