ADC Ready Enable.
ADC Start Enable.
Current ADC Status.
ADC Interrupt Flag.
ADC Reference Voltage Input Enable from P0[4].
ADC Input Clock Select.
ADC Result Value [1:0].

R/W(0)
R/W(0)
AD_EN
Cleared by H/W when AD_END goes to “1” from “0”.
0 = ADC is running now.
1 = ADC is idle state. ADC is stopped.
This bit must be cleared by software.
0 = ADC reference voltage from V
1 = ADC reference voltage from P0[4].
0 = System Clock (F
1 = PWM Input Clock (F

Set by hardware when ADC conversion has been finished.
Note that user should not use the AD_END but ADCF for finish of ADC conversion.
