TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless,
semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and
vulnerability to physical stress.
It is the responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards
of safety in making a safe design for the entire system, and to avoid situations in which a malfunction
or failure of such TOSHIBA products could cause loss of human life, bodily injury or damage to
property.
In developing your designs, please ensure that TOSHIBA products are used within specified operating
ranges as set forth in the most recent TOSHIBA products specifications.
Also, please keep in mind the precautions and conditions set forth in the
“Handling
Guide for
Semiconductor Devices,” or
“TOSHIBA
Semiconductor Reliability Handbook” etc. 021023_A

Caution in Setting the UART Noise Rejection Time
When UART is used, settings of RXDNC are limited depending on the transfer clock specified by BRG. The com-
bination "O" is available but please do not select the combination "–".
The transfer clock generated by timer/counter interrupt is calculated by the following equation :
Transfer clock [Hz] = Timer/counter source clock [Hz]
