8-channel 10-bit ADC (SAR Type)
Max. 104ksps(samples per sec.) @ FADC = 10MHz & 3V. (Max. 52ksps @ FADC = 5MHz & 3V)
AD_EN AD_REQ AD_END
SAR9
AD_EN : ADC Ready Enable
AD_REQ : ADC Start.
AD_END : Current ADC Status.
ADCF : ADC Interrupt Flag.
SAR[1:0] : Low Bits of ADC Result Value. (Total 10 bits)
SAR8
Cleared by H/W when AD_END goes to 1 from 0.
0 = ADC is running now.
User must check the ADCF instead of AD_END.
Must be cleared by S/W.
