Read
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
ADC
conversion. When the conversion is
finished, ADC
information can be available on P0.0 (see
the General-Purpose Input/Output section)
if enabled in the ADCCON register.
ADCDAT
0xFFFF0510
0x00000000
Read
ADCDAT is an ADC data result register.
Hold the 12-bit ADC result as shown in
Figure 21.
ADCRST
0xFFFF0514
0x00
Read/write
ADCRST resets the digital interface of the
ADC. Writing any value to this register
resets all the ADC registers to their
default value.
