ADCSTA Register
Name:
ADCSTA
Address:
0xFFFF050C
Default Value:
0x00
Access:
Read
Function:
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 can be available on P0.0 (see
if enabled in the ADCCON register.
ADCDAT Register
Name:
ADCDAT
Address:
0xFFFF0510
Default value:
0x00000000
Access:
Read
Function:
ADCDAT is an ADC data result register.
Hold the 12-bit ADC result as shown in
ADCRST Register
Name:
ADCRST
Address:
0xFFFF0514
Default Value:
0x00
Access:
Read/write
Function:
ADCRST resets the digital interface of the
ADC. Writing any value to this register
resets all the ADC registers to their
default value.
