Common IO Ports）：
IOA0： PWM output
IOA1： IR outputO ： output
IOA8、IOA10： Outer Interruption
IOA12~IOA15： SPI COM Port ，used to connect SPI FLASH
IOB0~IOB7： ADC Channel
IOA0~IOA15 can be both used as Waking IO Port
Note：1701A、1701B has 32 IO Ports including IOA0~IOA15, IOB0~IOB15
2701A、2701B has only 20 IO Ports including IOA0~IOA15，IOB0~IOB3
The only difference between 2701 and 1701 is that 2701 has no IOB4~IOB15
