assignment
• Power Input ( PWR_A , PWR_B ): (1,2)
• Analog reference voltage ( Ref ) : (3)
-It is analog reference voltage input block. Rhio represents voltage from 0 V to a reference
voltage in 1,024 steps. A reference voltage may not exceed 5 V. For details, refer to
section 3.4 ADC Input Port Setting.
• 5V Out : (4)
- It is AVCC output block. User can input the power of devices. Ground is no.5,7,9 and 11
blocks.
• Analog Input ( AI1 ~ AI4 ) : (5,6),(7,8),(9,10),(11,12)
• Digital Input ( DI1 ~ DI12 ) : (13,14),(15,16),(17,18),(19,20),(21,22),(23,24),
(25,26),(27,28),(29,30),(31,32),(33,34),(35,36)
Note : 1. Each Input is composed of one pair of upper and lower blocks.
2. Except for the no.3 and 4 input blocks, users can connect the wire to the blocks
without considering the polarity.
