Port 26 is A/D control register , when P26.3 (ADEN) is high A/D converter enable , P26.3 is low A/D converter
disable , P26.1(F_RUN) is high, select A/D conversion is free run , P26.1(F_RUN) is slow , A/D could not
convert P26.0(START) is high , A/D converter is only one time.

ADC Data Register (P12,P13)
When we use ADC , first ADC must get P12,P13 ,because P12,P13 share with SPI , ADC and HTC when
the A/D conversion is complete ,the result is load to the P12,P13, and the ADC can generate an interrupt (ADI),
the INT2_S ( P14.3) is set high.
