Cautions
1. Do not directly connect the output (or I/O) pins of IC products to each other, or to VDD, VCC,
and GND. Open-drain pins or open-collector pins, however, can be directly connected to
each other. Direct connection of the output pins between an IC product and an external
circuit is possible, if the output pins can be set to the high-impedance state and the output
timing of the external circuit is designed to avoid output conflict.
2. Product quality may suffer if the absolute maximum rating is exceeded even momentarily for
any parameter. That is, the absolute maximum ratings are rated values at which the product
is on the verge of suffering physical damage, and therefore the product must be used under
conditions that ensure that the absolute maximum ratings are not exceeded.
The ratings and conditions indicated for DC characteristics and AC characteristics represent
the quality assurance range during normal operation.

Notes 1. When A/D converter is used
2. When A/D converter is not used
3. During STOP mode (when only watch timer is operating), VDD = 3.5 to 5.5 V. Shifting to STOP mode or
restoring from STOP mode must be performed at VDD = 4.0 V min.
4. Shifting to IDLE mode or restoring from IDLE mode must be performed at VDD = 4.0 V min.
