Notes 1.  Connect the REGC pin to V
SS
 via a capacitor (0.47 to 1 
μ
F).  This value regulates the absolute maximum rating 
of the REGC pin.  Do not use this pin with voltage applied to it. 
 2. 
Must be 6.5 V or lower. 
 3. 
Must be 4.6 V or lower. 
 4. 
Do not exceed AV
REF(+) 
+ 0.3 V in case of A/D conversion target pin. 
 
Caution  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.  
 
Remarks 1.  Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port 
pins.  
 2. AV
