ADCSTA Register
Name:
ADCSTA
Address:
0xFFFF050C
Default Value:
0x00
Access:
Read only
ADCSTA is an ADC status register that indicates when an ADC
conversion result is ready. The ADCSTA register contains only
one bit, ADCReady (Bit 0), representing the status of the ADC.
This bit is set at the end of an ADC conversion, generating an
ADC interrupt. It is cleared automatically by reading the
ADCDAT MMR. When the ADC is performing a conversion,
the status of the ADC can be read externally via the ADCBUSY
pin. This pin is high during a conversion. When the conversion
is finished, ADCBUSY goes back low. This information is available
